The MacPorts 2.5.2 doesn't have my 64-bit hacks in it. I'm not sure  
what the consequences of 64-bit Python will be with respect to other  
Python packages, so I haven't committed the changes. And I ran into a  
problem compiling this on Tiger with GNU (non-Apple-patched) GCC 4.2.1.

But it's really 64-bit Python here, I think:

  $ /usr/bin/python -c 'import sys; print sys.maxint'

  $ /opt/casa/core2-apple-darwin9/3rd-party/bin/python -c 'import sys;  
print sys.maxint'

Here's the MacPorts port:

You might unpack this thing into your MacPorts tree like this:

tar xjvf ~/Downloads/python25.tbz -C $(port dir python25)/..

and then do a port update python25

... but I haven't tested that path.

I can post a binary on a web site if anyone is interested in testing  
this; it's a quad-architecture Framework build.

Be careful out there...
