Do other extensions build correctly? If so, it's beginning to look like a 
problem in numpy.distutils .

Hmm. That doesn't quite sound right, but it's been a while since I compiled the 
interpreter from source.

Makefile has most of that information. You can verify that distutils is finding 
it like so:

 >>> from distutils import sysconfig
 >>> sysconfig.get_makefile_filename()
'/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/config/Makefile'
 >>> d = sysconfig.parse_makefile(_)
 >>> import pprint
 >>> pprint.pprint(d)
{'AR': 'ar',
  ...
}

What versions of gcc and g77 are you using?

Yes, that is what I intended.
