[Pythonmac-SIG] Upgrading /usr/bin/python to 2.3.1?

[Bill Janssen]

I've got a software package (gamera.sf.net) that claims to need 2.3.1
on MacOS.  However, the python in /usr/bin/python is 2.3.0.

1.  Can it be upgraded?

2.  If not, can it be moved out of the way (/usr/libexec/ or
    whatever), and can I install a newer version in /usr/bin/?

3.  Is Apple going to upgrade it with Software Upgrade?
