There's a significant enough use case for wanting only qt3 or only qt4 on your system that it might be worth considering it. >> I think we should, however, do our best to avoid a situation where we have >> some ugly combination of USE="qt -qt3" or USE="qt4 -qt qt3"... > > right you are.

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
