I don't understand this statement. If you try to install a package you
already have installed yum will exit and tell you that it is already
installed.
If you try to install a package and you have an older version of it
installed, then yes, yum will update the package.

run yum upgrade


you can't do parallel installs of python 2.2 and python 2.3 - they
provide the same files.

why would you do this? forcing a package is a bad idea.

yes and a --force command, especially in this case would screw up your
system.
