The qt3 package in the [testing] repo has some major changes. The most important one is that it is now being installed in /usr instead of /opt/qt. To use the qt3 binaries, you need to use the -qt3 suffix (e.g.: qmake-qt3, moc-qt3, etc.) like it was done for the qt4 packages. The profile /etc/profile.d/qt3.sh was removed. The packages built against the qt3 in [extra] should continue to work without any rebuild necessary. They will however need to be fixed to build against the new qt3 but I have build fixes for all the qt3 packages in the repos. I will push these fixes in svn once qt3-1:3.3.8b-4 will move to [extra] in a few days if there are no issues. Eric
