[Pythonmac-SIG] pthread problem

[bob ackerman]

osx 10.1.2, sendmail-8.12.2, milter-0.3.9, python2.1
when i run sample.py i get:
dyld: python Undefined symbols:
_pthread_sigmask
_sigwait

does this mean i haven't built python correctly or that i haven't built my 
milter module correctly?
i added 'pthread' to libs in setup.py, but it said everything was up to 
date, so it looks like i have to rebuld python, unless someone tells me 
otherwise.
