Yes, python 2.4 is a hard requirement (2.4.4+).
What distribution are you running mostly?
It's not required to port a package that adapts python to the 
distribution's convention. It's enough to build a package that installs 
the compiled python distribution into a specified directory.

I usually compile python 2.4.5 on the machines I deploy plone on into a 
directory below /srv/zope even if there is a system python2.4.

The simple story is
bin/instance stop (stop zope)
svn up
bin/buildout (update the dependencies)
bin/instance start (start zope again)
+ check if the plone instance is responding in the case development 
broke the site.

For wgo we use a stable plone release. Only the wgo specific packages 
are from svn. The application server environment is build with 
zc.buildout. It pulls in all dependencies we define during development.

http://plone.org/documentation/tutorial/buildout
http://pypi.python.org/pypi/zc.buildout

Buildout is also used by most plone developers in depoyments to 
compile/install/configure/update all other components (zope, 
squid/varnish, pound, apache, ngnix, ...). Not really Plone/Zope 
specific, but of cause unusual for a (non plone) server administrator.
There are no good distribution specific packages for zope/plone and some 
distribution screwed up the system's python in the past so it became the
standard deployment in the zope/plone world.
