I don't have Qt installed anywhere, so I can't reproduce that problem. I 
also don't see that particular version of qt-script in the tree, so I 
can't be sure, but my guess is some Qt dep that you already have 
installed depends on a newer version of udev than you will be getting 
after the downgrade, thus requiring it to downgrade as well.

Yes, I expected something like that. In all likelihood, you'll need to 
completely remove sys-fs/udev and virtual/udev and then reinstall the 
older version. You'll probably want to do this in single user mode (i.e. 
`rc single`), so running programs don't crash suddenly. A reboot 
afterward is probably a good idea as well.
