Ah that's pretty cool- will be worth remembering. I was just being stupid
though, I just downloaded python for i386/ppc from python.org. I thought I
already had that one but I must have had the other x86_64/i386 one. Whoops.

All is working perfectly now :D - Thank you so much again for all your help
and work on the project!
