Running multiple versions of Python on the same host..

[Cowmix]

For my day job I am forced to run RHEL3 (and Centos3 on my desktop). I
want to be able to use a few applications that require Python 2.4.X but
RHEL3 ships with Python 2.2.3. I have tried to install and upgrade
Python 2.4.X many ways like using PyVault and doing a source based
install but each way has been fraught with problems from weird
dependency issues to screwing up 'yum'.

What is the best way to run multiple version of Python on the same
system?

thanks!

You could use chroot. Ask if you want more details.

Did you use the bootstrap RPM?

http://www.python.org/pyvault/centos-3-i386/pyvault-release-bootstrap-3-3.el3.pyv.noarch.rpm

If you want to try again, you can ping the pyvault-users mailing list
for specific answers to error messages you are seeing during
installation.

If installing from source, 'make altinstall' will do everything but
link python to (for example python2.4. You can then run 'python2.4'
'python2.3',etc to use a particular version.
