So, libpthread.so.1.60 should be linked against my program, but
libpthread_pic.a is what should be loaded at runtime?

This is the results I get when running "ldconfig -r | grep pthread":

search directories: /usr/pkg/lib:/usr/local/lib:/usr/local/pthreads/lib:/usr/local/pthreads/lib
23:-lpthread.1.60 => /usr/local/pthreads/lib/libpthread.so.1.60

yes, I've already done this.

No, not any other place other than the directory I built the libraries
in.  I've searched the entire drive (its not a big one) using find.  Any
other ideas what could be going wrong?
