[Pythonmac-SIG] How to build Python 2.5 to support 64-bits on Mac OS X 10.4

[Alexandre Parenteau]

Harold,

Thanks for the information. It sounds like I might be more lucky to try 2.5
on Leopard (I don't know what will happen for Carbon, because regardless of
64bits, it is being deprecated anyway).

I will also send information when I get to try it.

Thanks!
alex
