Tom,

RedHat 9 ships with python 2.2.2 in /usr/bin/python (also
/usr/bin/python2  and /usr/bin/python2.2 - they are all the same thing!

RedHat 8 has the same setup but it is version 2.2.1 so no problems with
that

If you are going to install 2.3.* then I would (and have) put it into
/usr/local/ as this will not cause any problems with the RedHat
applications that use python.  If you put it into /usr/bin as python or
python2 you will end up having to compile all the extensions that RedHat
ships with python (PyGTK, M2Crypto... and a whole lot more) 


All in all it may be worth sticking to the RedHat python (2.2.2 / 2.2.1)
for the short term (till RedHat 10?) especially if you are releasing
these programs to other people/platforms....


HTH
Martin
