I just wanted to chime in that I have had the same problem on a PPC
Mac and on an Intel Mac.  My workaround with the iBook (PPC) was to
compile Python 2.5 from source.  I'll probably do the same on my MBP
(Intel), but that's rather inconvenient.  It'd make me quite happy if
someone could help Nik and I.

As an aside, on my MBP, I am testing (for work) the Python 2.3 that
shipped with OSX 10.4.  Despite the numerous warnings I've found
online not to use it, I have found that numpy, scipy, and matplotlib
work just fine with 2.3, but I will have to do The Readline Fix in
order to make interactive sessions at the command-line usable.

Thanks,
Nick
