With Debian and Ubuntu -- and I assume Fedora, SuSE, RHEL, using yum --
you just have to create a deb with all the right metadata, so there is
no problem building a SCons deb for Python 2.6 and 2.7 and one for 3.2
and soon 3.3.

The problem though will be the codebase, unless there are two it will
have to be Python 3 and Python 2 compliant.

A SCons tool for creating debs is clearly something that needs
reviving... I have a plan.
