Compiling qt-3.3.8-r4 fails due to a name clash with xorg-server-1.4.0.90-r3. I could resolve the problem by adding -DQT_CLEAN_NAMESPACE to the configure call in the qt ebuild file. Error Output: ...

Actual Results: compiling qt fails and so also KDE cannot be installed/updated The Qt define QT_CLEAN_NAMESPACE fixes the problem.
