I think you meant: fat == ppc + i386.

However, it's also possible to build binaries with ppc, i386 and
x86_64 - as are shipped with Mac OS X 10.6, so "fat" is not really
well-defined and could lead to trying to install 32-bit software for
a 64-bit build of Python.

IMHO, it's better to list the actually supported architectures
as e.g. "darwin-i386-ppc" or "darwin-i386-ppc-x86_64".
