/usr/ports/net/freeradius (port version 1.0.2_1) doesn't build if libradius is already installed on the system.

The linker exits with an error while compiling 'radwho' module:

Stop in /usr/ports/net/freeradius.

so it seems like freeradius-port conflicts with itself.

After '#make deinstall' the problem didn't appear.

And, for one-time build-and-install the port behaves well. For furter compiling (i.e. making a package for fast-installation of a second-third-... server while the main has already the port installed) the port doesn't compile.

Fix: As it seems to me, the linker-library path in
'cc -rpath=/usr/local/lib -L/usr/local/lib  -L../lib -o radwho radwho.o mainconfig.o util.o nas.o client.o log.o conffile.o files.o xlat.o -lpthread -lcrypto -lssl  -lradius'
should be corrected - instead of '-L/usr/local/lib -L../lib' it should be reversed to '-L../lib -L/usr/local/lib' so the linker first checks for 'libradius' in src/main/../lib (which compiles earlier) and so for all the objects, referenced by that library (which also compile into src/main/../lib).

A sample patch, which works fine for me:
How-To-Repeat: #cd /usr/ports/net/freeradius
#make install clean
#make build

This will repeat the problem.
