Description of problem:Upgrading from F7 to f8 yum is broken.


Version-Release number of selected component (if applicable):


How reproducible:every time


Steps to Reproduce:
1.[root@fedora etc]# yum -y upgrade
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:
2.5.1 (r251:54863, Oct 30 2007, 13:54:11)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-33)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq

I have tried all the suggestions I can find and am still receiving this error. 
Also, there does not exist a python-elementtree any longer.

Python import log
[root@fedora etc]# python -d
Python 2.5.1 (r251:54863, Oct 30 2007, 13:54:11)
