[Pythonmac-SIG] 64-bit Python?

[Chris Kees]

I'm wondering how to coordinate having python executables in 32 and 64  
bit mode on the same machine. Will the patched python 2.6 build a  
python and a python64? When I build extension models do I then need to  
build/install each module  twice e.g. 'python setup.py install' and  
'python64 setup.py install'? Could I help this effort out by starting  
to work with your branch of python 2.6? I've been building a non- 
framework, non-universal build of python to work in 64 bit but it  
would be nice to take advantage of the universal build stuff as well  
as use some gui tools in 64 bit.
