Python embedding & question about autoconf and dynamic linking

I am myself into the same situation...
I am trying to link my C application against libpython and I get unresolved symbols with
posix thread related symbols. Why the heck would I need the posix thread library if I never
create any thread ?!?

Why is it so difficult to do something as common as this?
