[Zope] Python Upgrading for Zope 2.0

Greetings, After download the new python(1.5.2) from the web site and installing the RedHat RPM I still get 1.5.1 listed upon firing up python from the shell. Example: Shell> python

...

Python 1.5.1 Ctrl-D to exit But when I fireup Zope 2.0 and look in the control-panel it tells me that I am running 1.5.1. Do I not have Python installed correctly?

Also, I see that there may be a users group in Portland OR? Does anyone know about this? DC
