I usually locally build all ports but decided to install lang/squeak to check an issue reported on a mailing list.  Unfortunately, pkg insists that it needs to be reinstalled, even after being freshly rebuilt:

server% sudo pkg install lang/squeak

The only obvious difference is the requirement for libexecinfo.so.1 in the installed version.  The reason for this is unclear - it's not listed anywhere in the Makefile, though the configure script does test for it.  It's present in the base system, though I also have libexecinfo-1.1_3 installed (as a requirement for llvm and samba) and ldd shows pkg is relying on the port:

server% ldd /usr/local/sbin/pkg   
/usr/local/sbin/pkg:
        libpkg.so.3 => /usr/local/lib/libpkg.so.3 (0x80086f000)
        libelf.so.1 => /usr/lib/libelf.so.1 (0x800c3e000)
        libexecinfo.so.1 => /usr/local/lib/libexecinfo.so.1 (0x800e53000)
        libfetch.so.6 => /usr/lib/libfetch.so.6 (0x801056000)
        libutil.so.9 => /lib/libutil.so.9 (0x801268000)

A friend who has also built pkg reports the same behaviour.
There are multiple issues here:
- Why is a freshly built pkg reporting it needs to be reinstalled?
- Why doesn't pkg report details of why it needs to be reinstalled? Which shared library has changed and how?
- Why is pkg linking against a library not listed as a dependency?
