I'd like to tell you what I've tried and then I'd really welcome any comments you can provide on how I can get PortAudio and PyAudio setup correctly!
I've tried installing the stable and svn releases of PortAudio from their website for my Core 2 Duo MacBook Pro running Snow Leopard. The stable release has a sizeof error that can be fixed(?), but the daily svn release installs fine with ./configure && make && make install (so this is what I'm using). The tests are compiled properly and I can get the binaries to produce output/can read microphone input.
Ok, so then PyAudio has troubles. Installing from source I get errors about not finding the libraries:

I can install PyAudio from their .dmg installer, but it targets python2.5. If I copy all of the related contents of /Library/Python/2.5/site-packages/ to /Library/Python/2.6/site-packages/ (this includes PyAudio-0.2.3-py2.5.egg-info, _portaudio.so, pyaudio.py, pyaudio.pyc, and pyaudio.pyo) then my python2.6 can recognize it.
In [1]: import pyaudio
Please build and install the PortAudio Python bindings first.

So this happens because _portaudio can't be imported. If I try to import that directly:
In [2]: import _portaudio

Ok, so if I export VERSIONER_PYTHON_PREFER_32_BIT=yes and then run python again (well, ipython I suppose), we can see it works but with consequences:
In [1]: import pyaudio
In [2]: pyaudio
Out[2]: <module 'pyaudio' from '/Library/Python/2.6/site-packages/pyaudio.pyc'>

We can assume pylab was working before! I spent a while getting this far, but can someone help with this install or lend advice from a successful Snow Leopard install? Sorry for the long post, but I'm notorious for only giving partial information and I'm trying to fix that!
