The repo db should always only refer to the latest version of a
package, all other packages are obsolete.  Calling repo-add on a
package will *replace* any previous entry, and there can be at most
one previous entry.  So finding out which package is obsolete is
actually fairly simple.

Please take a look at the script I attached to my previous email in
this thread, I think it'll only need minor modifications to do this.

Perl is another example of filling a tiny, short-term need, and then
being a real problem in the longer term.
