I tried to build a fresh ~amd64 gentoo with kde4 and on that way I got the problem, that qt-gui-4.5.2-r1 wanted to be emerged, but at the same time also qt-gui-4.5.1-r2 was pulled in. After some checks I realized that qt-gui-4.5.1-r2 was pulled in because it has automatically the dbus use flag enabled, but qt-4.5.2-r1 was pulled in because it is the most recent ~amd64 version. After compiling qt-4.5.2-r1 with the dbus use flag enabled, the problem was gone and I was able to emerge kde4 without any further problem. The problem is, that qt-4.5.1 and qt-4.5.2 cannot be installed at the same time... Reproducible: Always Steps to Reproduce: 1. Start with a fresh stage3 and fresh portage tree 2. Do NOT set the dbus useflag for qt-gui 3. emerge -a kdebase-startkde Actual Results: Blocking packages Expected Results: No blocking packages :P
