Python 2.1 and 2.2 will live side-by-side on a linux machine - they install 
their libs in /usr/lib/python2.1 and /usr/lib/python2.2.

The most important thing to watch out for is the python executable itself 
(typically /usr/bin/python).

To have both installed, make a copy of /usr/bin/python to /usr/bin/python2.2 - 
then you'll be able to run apps using 2.2 with that binary. Once 2.1 is 
installed, move it to /usr/bin/python2.1 and symlink whichever is more 
convenient to /usr/bin/python. You should be able to get zope to start up 
using /usr/bin/python2.1 if you want to keep /usr/bin/python symlinked to 
2.2.
