I've not done this but I saw no immediate reply. So I thought I'd pass
on a thought that might be viable for you.

First, I wrote some scripts long ago that encountered the variability of
versioning against source tarballs. So I _feel_ your pain.
Unfortunately, those scripts are off line for now. Meaning: HDs are not
in any system and not labeled so I can't quickly pull them up and pass
them on to you. Sorry.

But here's my thought.

Why not just get a complete list and sort them down into a file. Then,
using your editor-of-choice, delete the ones you want to keep. In a few
hours or so, you should have a list of those to delete. Turn those into
commands, like rpm --erase <full-versioned-package-name> and run it.
Make sure you are well backed-up first, of course.

With typical expertise in a reasonably powerful editor, like vi(m),
after the manual deletes from the file it should go quickly.
