That's because there is no separate libpthreads.so under FreeBSD.
Instead you use the -pthread compiler flag, which causes (inter alia)
the linker to use the reentrant version of the system library,
libc_r.so. (libc_r.so contains all the pthread_foo() functions,
unlike the standard libc.so).
Now, compiling generic programs using pthreads under FreeBSD 4.x tends
to get in a bit of a tangle unless the authors or port maintainers
have seen fit to provide FreeBSD support specifically (usually a claim
of "thread support" means "thread support on Linux"). Avoid threaded
versions of software that aren't documented as usable under FreeBSD
unless you like knotty problems.
Cheers,
Matthew
