The perl-BerkeleyDB package over at Dag's repository.  I've tried 
reinstalling it from source rpm and the db4 package from CentOS, but 
that doesn't help.

At this point, I wonder if it would be a magnificent disaster to just 
download all the base rpm's, the updates rpm's, and just do a massive 
"rpm -Fvh --force" on everything.
