If x11-libs/qt-4.5.0_rc1 is installed, trying to emege x11-libs/qt-demo tries to downgrade to qt-4.4.2-r1, which seems ok because x11-libs/qt-demo-4.4.2 Reproducible: Always Steps to Reproduce:
qt-demo-4.5.0_rc1 is not in portage, because it fails to compile. We will look into this, but it has low priority. We hope to offer an upgrade to qt-demo-4.5.0 with the final release next month.
I added fixed qt-demo-4.5.0 ebuild in qting-edge overlay :)
Re-opening as now we are ready to mark this as "solved". Thanks Alex
