[Yum] Yum Error

[Eric Myers]

Can you help me with this error?  I am running Centos 4.2.
===================================
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

    /usr/lib/librpmdb-4.3.so: undefined symbol: 
__dbcl_db_reMove_redFrpmdb

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:
2.3.4 (#1, Feb 22 2005, 04:09:37)
[GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)]

If you cannot solve this problem yourself, please send this
message to <yum at lists.linux.duke.edu>.
