[Pythonmac-SIG] Official 'right way' to create a universal build of Python?

[Ronald Oussoren]

Mark,

If you're only testing I'd lose the --enable-framework bit and create  
a regular unix install. That way you won't mess up any regular python  
install's you have (such as Python.org binary install), and you can  
just copy the sys.prefix to the other machine.
