RPM database issues come up in a variety of ways.  For some reason, 
Paul's response above prompted me to consider why it would not be 
possible or easier to edit the RPM database.  Perhaps that question came 
to mind today because I have been considering switching from Up2date 
upgrading to use of Yum and have the impression that Yum updates are 
also not recorded in the RPM database.
