This error occurs if you are trying to link two different thread libraries 
together. (As in libpthread, libc_r, libthr).
You can try to find out the offender with ldd on the shared libraries. 
(libgthread-2.0 looks suspicious)

Did you update the machine from an older version (like 5.2.1)?

On FreeBSD we usually advise people to recompile all programs that use
threads after upgrading to 5.3, or use the libmap trick if they are lazy.
