the version of python that is in the update( or base RHN ) repo
-- it is a MUST USE --
yum and gnome both require that very specific version .
If a different version is installed "on top" of the required version yum and some of Gnome will not work !
Now you can install a second version of python next to
the needed one
say in /opt/python2.7.3 or /lib64/python2.7.3
from your first post
I didn't know the printer config program used python.
that is one of the things in gnome that WILL break from using a different version of python than is in the RHN repo
you might want to contact red hat tech support
they can point you to the needed rpms to reinstall the required version of python
i am betting you will get a error if you try this
a long output of python errors
