[CentOS] Pyhton Install location/building rpm

Hello All

I need to install Python 2.4.2 for installing Zope. What is the
location for python that should be given in the ./configure --prefix
directive?

/usr/lib is for python libraries..isn't it and thats where I find most
of python installed except for the python binary in /sbin

Should I uninstall the normal python installed in Centos 4.2 by
default before installing from source?

Can someone guide me about how to create a source rpm for Python &
Zope and where to find the spec files? Please note that this is my
first attempt at building rpm of any kind, so please give me links
accordingly. I would like to maintain latest stable release of Python
& Zope and if possible, build their rpm and contribute the same to
centos contrib repo, since I will be building it anyway. Please guide.
I will also need someone to test the rpm, before releasing into
contrib, if it is wanted.

With regards.
Sanjay.
