[Bf-committers] Moving to Python 3.2.x

[Davis Sorenson]

As Tobias mentioned, Python 3.2 is often available in development
repositories, in Ubuntu's case at packages.ubuntu.com (
http://packages.ubuntu.com/natty/python3.2 ) and at packages.debian.org for
Debian ( http://packages.debian.org/sid/python3.2 ) although Ubuntu being
based on Debian they are most likely almost identical.

I have to agree that this upgrade seems a little bit hasty, with none of the
big distros supporting 3.2 in their main repos, but I would guess that the
purpose of this is to get Blender working bug-free with Python 3.2 before it
becomes more of a standard.
