This seems to be a known problem (at least to some people on IRC), but I can't find it in the bug database, so I'll go ahead and report it. Some recent changes in portage resulted in this problem: ebuild U ] dev-python/PyQt4-4.5 [4.4.4-r5] USE="X dbus kde opengl qt3support svg webkit -assistant -debug -doc -examples -phonon -sql -xmlpatterns" 6,780 kB [blocks B ] >=dev-python/PyQt4-4.5_pre1 (">=dev-python/PyQt4-4.5_pre1" is blocking kde-base/pykde4-4.2.4) Total: 7 packages (7 upgrades), Size of downloads: 16,142 kB Conflict: 1 block (1 unsatisfied) * Error: The above package list contains packages which cannot be * installed at the same time on the same system.

Perhaps some more proper solution should be created. Thanks. Reproducible: Always
it will not be blown away. Use /etc/portage/package.mask. However, this should be fixed...
This is a duplicate of bug #273473 , see also bug #273510 for package.mask entries if you want to keep kde-base/pykde4.
