libxml2mod.so : undefined symbol

[Murali Potla]

I have problem with redhat-config-packages and yum on my FC1. it looks
like it is a problem with the python and libxml2.
I have upgraded my box from Red Hat linux 9 to Fedora Core 1.

I am getting the following error whenever i launch yum or
redhat-config-pcakages 

import libxml2mod
ImportError: /usr/lib/python2.2/site-packages/libxml2mod.so: undefined
symbol: xmlTextReaderIsValid

I am unable to use these tools. command line rpm works fine though.

Are there any issues reported while upgrading from RHL to fedora ?
