Re: thread_test.c problems

Yep, that looks like a mess.  Not sure why it is happening but in this
example libcrypto and libkrb5 both have _des_crypt:

> /usr/lib/libkrb5.dylib(ProjectBuilderMasterObjectFile.o) definition of

It seems -lkrb5 also contains the -lcrypto routines.  If you compile
without -lcrypto, does it work?  If you modify Makefile.global and
remove -lcrypto:

    LIBS = -lssl -lcrypto -lz -lreadline -ltermcap -lgetopt -lcompat -lipc -ldl -lm -lutil

does it work?  It might, based on those warnings.

Fortunately, it is not related to threading.
