Bugzilla Bug 158149

app-admin/keepassx-0.2.2 needs qt3 support, so if you only have qt4, you need
the qt3support use flag when emerging qt. Kind of time expensive to have to
re-emerge qt4.

Erm, the check is broken :)

-if has_version >=x11-libs/qt-4.2.2 && built_with_use qt qt3support; then
+if has_version >=x11-libs/qt-4.2.2 && ! built_with_use qt qt3support; then

What a stupid mistake...fixed for sure.
