CentOS 5 :: Yum Broke After Update And Installing MySQL TOP

After updating and installing Mysql's TOP, yum broke. When trying to clean, update, or install, the following error occurs:

dingle@its:/home/dingle# yum update
There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named cElementTree
Please install a package which provides this module, or verify that the module is installed correctly.
It's possible that the above module doesn't match the current version of Python, which is:
2.4.3 (#1, Sep 3 2009, 15:37:12)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)]
If you cannot solve this problem yourself, please go to the yum faq at: [URL]

I tried to resolve by reinstalling the dependency, didn't work either:
dingle@its:/home/dingle# rpm - [URL]

package python-elementtree-1.2.6-7.el4.rf.i386 (which is newer than python-elementtree-1.2.6-5.i386) is already installed

How can I rebuild YUM appropriately so it will operate correctly?
