There's a significant enough use case for wanting only qt3 or only qt4
on your system that it might be worth considering it.

Agreed on this. So right now, we've got a couple of options.

- Use case is user wants program with its best qt. USE=qt is an easy
option. The other option is USE="qt3 qt4", and apps should always pick
the best of the enabled qt versions if they are mutually exclusive.

- Use case is avoiding installing either qt3 or qt4. Impossible with
USE=qt, possible with USE="qt3/qt4".

Thanks,
Donnie
