Yum on CentOS 4 is built for Python 2.3. By upgrading it, you broke it and
probably most of the configuration utilities as well, since they all use
Python. CentOS/RHEL expects a working Python 2.3.

If you need Python 2.5, I suggest you install it in parallel and return 2.3
to a working state. If you just need yum, rebuilding it against 2.5 would
probably work, but I wouldn't trust having a system with a broken/unxepected
