Installing Python modules as RPMs when there are 2 interpreters installed!

[John]

I have a Linux machine (Red Hat 7.2) that has Python 1.5. I installed
Python 2.2 later. It is problematic to remove 1.5 since quite a few
tools depend on it. Now I need to install some modules (as RPMS) on
2.2 for my work. But they are getting installed on 1.5. How can I
specify 2.2 as the target.

Thanks
