Hmm...I was poking around in the finder on a display of new
iMacs at Best Buy last saturday. I searched for "python" and
it took me to a directory listing with three items:
Python 2.3
Python 2.4
Python 2.5

It's possible that Python 2.6 is located somewhere else. I assume
that Snow Leopard was installed, but I didn't actually check that.

But it doesn't say whether that disk image is compatible with
Snow Leopard and I don't take such things for granted.

Ok, now I know. Thanks for the information.
