First stab at a Makefile that will create a MacPython that uses the

Apple-installed Python 2.2 from /usr/bin as it's underlying engine.
All the MacPython stuff is installed into /Applications/MacPython-OSX,
and .pth files and other magic are used to tie everything together.

So far only the raw windowing interpreter and BuildApplet work.
