Coolness - I was able to get a clean build of python for the i386 arch 
just now.  I did have to apply a patch to Lib/plat-mac/applesingle.py so 
that it would run without errors.  I got the required patch from 
http://www.opensource.apple.com/darwinsource/tarballs/other/python-16.tar.gz 
that Kevin mentioned in an earlier post to this thread.

Now to build the rest of our app and see how it fairs ;)
