I was also bit by the same problem.
As far as I understand, it was introduced to the XFree-4.0.2 with Xthreads
addition. Please correct me if I'm wrong.
/usr/ports/x11/XFree86-4/files/patch-xthreads
Backing out this patch breaks things, for example graphics/xine.
The fact is, the Mesa gets built with threads, so the app has to be linked
with -pthread.
(BTW, have XFREE86_VERSION=4 in /etc/make.conf if you're using XF86 4.x)
Since it's Mesa related (and it needs to be installed for GLU), all applications 
that depend on it fail, for example - /usr/ports/palm/pose :(
Maxim, do you have any ideas about how to fix it?
