I've just upgraded from qt-3.3.6-r2 to qt-3.3.6-r3. When I try to reemerge kdelibs-3.5.5-r2, portage wants to downgrade qt again to 3.3.6-r2. In the kdelibs ebuild I can only find RDEPEND="$(qt_min_version 3.3.3) ..." so I don't understand the reason for the downgrade.
Fixed in qt3.eclass, thanks.
Thanks for the quick solution, it's much appreciated!
