My goal is first to get Python building on 10.4 (i386 arch) and then to 
worry about multi-arch binaries.

Once that happens I can start to do the steps to build multi-arch, but 
that is a secondary goal because I think we could live with different 
downloads for ppc and i386 for the short term.

If the binaries I build are useful I can make them available if that helps.
