redhat-config-packages and yum broken with libxml2mod

[Murali Potla]

Hello list members,

I am new to the list. 
I have problem with redhat-config-packages and yum. 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 

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.
How to break this out 

Regards
Murlai
