Pthread Issues

Current folks--

I'm having some major issues with pthreads.  I have a base 5.2 cvsupgraded to 5.2.1.  To save a lot of copying and pasting and keep this message from being too long, please check:

and

for more information that might give clues to some of the issues.

At someone's request tried the following (in /usr/ports/net/openldap21-client)

shocker1# make -VOSVERSION -VPTHREAD_CFLAGS -VPTHREAD_LIBS
502010
-D_THREAD_SAFE
-lc_r

Someone else suggested creating a /etc/libmap.conf with the following:

libpthread.so.1         libc_r.so.5
libpthread.so           libc_r.so

None of this has worked, however.  It was mentioned to me that "checking for pthread_create in default libraries" is supposed to be successful, so maybe something went wrong with my base system upgrade.

I have no idea, personally.  Anyone that could help me out, it'd be much appreciated, as I'm pretty much barred from upgrading a significant number of my ports beause of dependencies on the ones that are failing.

If there's any other information that would be helpful, please let me know.

Thanks,
Jeff
