I finally got hold of a Mac that can run 10.4 and was finally able to
build a new binary installer for Python 2.6 (as well as one for PIL
1.1.7) is truly compatible with Mac OS X 10.3.9.
For now it is available here:
<http://www.astro.washington.edu/users/rowen/python/>
though I hope it will end up on the official site at some point.
I have not tested the wx back end and would be grateful if somebody had
time to do so.
I attempted to build a binary installer for Python 2.5.x but ran into
problems: Mac binaries for Python 2.5 aren't compatible with 3rd party
versions of Tk, which causes a mess for matplotlib. There are
workarounds, but given the state of Mac python 2.5 I'm not sure it's
worth the bother.
I propose not having a matplotlib binary installer for Python 2.5 and
getting a pair for Python 2.7 32-bit (10.3.9 and later) and 64-bit (10.5
and later).
What do others think?
