Easy answer: Working on Qt3 and Qt4 at the same time. You know yourself
the upgrade path isn't easy so its needed to be able to maintain a Qt3
version of your app for some time. And having to setup a second system
for this is just a PITA.

Yes, you could simply put the Qt4 into /usr/share/qt4 or some such, but
then its harder to access it. I find the solution to add a -qt4 suffix
very good.


A visit to a fresh place will bring strange work.
