Is this PR still relevant?
I never achieved to reproduce it.
This issue is reproducable - it's an interaction between gpsd's scons build system and the pkg-config files of devel/ncurses. To put it the other way round, it is _only_ reproducable if you have devel/ncurses installed. I came across this when rebuilding gpsd-3.14 after today's upgrade to ncurses-6.0.
Gory details ahead: ncurses.pc has "-rpath /usr/local/lib" in it's Libs: line. Scons tries to parse the pkgconf output but does not know about "-rpath". OTOH, it expects C compiler flags, not linker flags; and all other .pc-files at hand have "-Wl,-rpath -Wl,/usr/local/lib", so I guess it's really ncurses which is at fault here.
Attached file has to be dropped as devel/ncurses/files/patch-misc__gen-pkgconfig.in. It makes sure ncurses pkgconfig files are in line with all other pkgconfig files, and gpsd finishes scons.
Note there's another patch neccessary to make gpsd build successfully, but as this is more of a ncurses issue than a gpsd issue, I'll submit that in a seperate PR shortly.

Cc'ing devel/ncurses maintainer
Actually the bug in is scons because the -rpath is passed when asking for libs while here scons should request cflags in that case.
So either scons or the sconsfile in gpsd has to be fixed imho not ncurses.
While here reopen to track it
There's two points against that:
- all other available .pc-files use the -Wl construct - that is, it's silently (I couldn't find any explicit documentation) assumed that $CC is used for linking, so that all linker arguments have to be in CFLAGS format. Even the pkg-config guide assumes that the pkgconfig output will be used on the cc command line: http://people.freedesktop.org/~dbn/pkg-config-guide.html#faq FAQ 1 - but there's no clear word on wether to use ld(1) or cc(1) style arguments.
- scons itself does ignore "-rpath" by design. Deep down in it's Environment.py a comment states (ll.691):
#[...] It particular, if the
# flag is not known to occur in a config script and there's a way
# of passing the flag to the right place (by wrapping it in a -W
# flag, for example) we don't check for it.

[patch] improve freebsd rpath usage in devel/ncurses configure
The cases that use ld(1) directly are vanishingly small, so having '-Wl,-rpath,' in the .pc file rather than '-rpath ' seems far better - for any software using pkg-config --libs.
While scons could be fixed to convert any '-rpath foo' it sees to '-Wl,-rpath,foo' (especially since smart_link() in link.py invokes cc by default (and never ld unless the user perversely defines CC=ld), it's a fact of life that it doesn't do such a conversion right now.
So I vote we patch ncurses and move on so gpsd is fixed when the ncurses package is installed.
Attached is an alternate patch that fixes the freebsd case in the ncurses configure script - it may be more palatable and could be fed upstream to ncurses.
It's more correct than just -rpath since the vast majority of possible consumers of 'pkg-config --libs' flags will be linkers invoked by 'cc' or 'c++'. And the bare -rpath will cause those to fail, not just those wrapped by scons. How often do we see a port invoke ld(1) directly to do the linking?
Maybe scons could be convinced to improve their arg parsing as well (convert any '-rpath foo' it might see to Wl,-rpath,foo), but that doesn't solve the issue for any non-scons user of the 'pkg-config --libs ncurses' flags. Seeing as there have been likely few other reported failures due to this issue, the number is probably low, but we should fix ncurses for freebsd, IMO.
poudriere build of scons + ncurses (with attachment 165695 [details]) + gpsd passed.
The same ncurses + attachment 165695 [details] was used to build lang/python27 & lang/python34 in the poudriere jail as well - also passed.
Any chance we can fix ncurses (per the patch in comment 9)? This issue has been hanging around forever. ncurses is the only port that I have seen that installs a .pc file that uses bare -rpath rather than -Wl,-rpath.
Yes, gcc on freebsd (but not linux) does accept a bare -rpath (as does clang), but -Wl,-rpath is generally preferred. Even the support for -rpath on gcc/freebsd doesn't document -rpath in the man pages or info pages (maybe it did at some point in the distant past?).
No one has come forward with a patch to scons to make it somehow accept bare -rpath (maybe convert it to -Wl,-rpath??). And the comment in scons seems to indicate the burden is on the user to not pass in things that should be wrapped by -Wl.
I'm sure scons could be improved here (at least a better error message), but considering the expectation of the usage of the linker flags in most .pc files (that it is called from cc(1), not ld(1)), I think there's a case to made to update the ncurses configure script on freebsd such that it is consistent with the preference for -Wl,-rpath.
Similar patch from comment 9 submitted upstream to ncurses:
(In reply to John Hein from comment #11)
Yes it makes sense to make such patch in ncurses and it makes it consistent with other plateforms (it uses that on linux or netbsd for instance)
As soon as I have enough time I will commit this.
Sorry for the delay

Change to -Wl,-rpath for FreeBSD applied upstream (ncurses-6.0-20160220):
(In reply to Baptiste Daroussin from comment #13)
Baptiste, should I open a new ncurses bug for the ncurses patch here?
(In reply to John Hein from comment #15)
Separate bug opened for the -Wl,-rpath fix to devel/ncurses so this doesn't get lost in a bug report for a different port:
This can be closed now. The ncurses port was fix per bug 209526.

[patch] improve freebsd rpath usage in devel/ncurses configure
This patch was applied a while ago to the ncurses port (per bug 209526) - mark obsolete.
(In reply to John Hein from comment #17)
In case a bug editor comes along, this should be closed as "FIXED".
See previous message. I think this could closed.
ok, I heard you :)
