hmm -- this all may be a trick -- both the *.mpkg and the standard
build put everything in /Library/Frameworks/Python -- which is where
it belongs. Bu tif you need root access to write there, then there is
a problem. I'm sure a non-root build could put everything in the
users' home directory, then packages built against that would have
their paths messed up.

What's odd is that I'm pretty sure I've been able to point+click
install those without sudo...(I could recall incorrectly).

This would be a good question for the pythonmac list -- low traffic,
but there are some very smart and helpful folks there:

It should be possible to unpack a mpkg by hand, but it contains both
the contents, and various instal scripts, so that seems like a really
ugly solution.
