I don't think the issue here is building -- I think the eggs that are 
built do work -- the issue here is easy_install knowing what to look 
for, and being able to find that, in the case of a Universal build.

It seems when you run "easy_install matplotlib", fro man intel machine 
-- it goes and looks for a i386 binary, and when you run it from a PPC, 
it looks for a ppc binary -- and in neither case does it find the 
Universal one. So we need to either:

1) Know it is a Universal build of Python, and thus look for, and finid, 
a Universal binary.

2) Or accept a Universal binary when it is looking for either an Intle 
of PPC version.

I like the first option better, but have no idea how all this works.
