Large numbers of missing Dependencies upon update

[marko]

I'm having rawhide update problems lately with missing dependencies,
and because of this I have to --skip-broken all these:

control-center.x86_64 1:2.27.3-1.fc12
control-center-filesystem.x86_64 1:2.27.3-1.fc12
gdm.x86_64 1:2.26.1-12.fc12
gnome-applets.x86_64 1:2.27.3-3.fc12
gnome-screensaver.x86_64 0:2.27.0-2.fc12
gnome-settings-daemon.x86_64 0:2.27.3-2.fc12
kdebase-workspace.x86_64 0:4.2.95-5.fc12
kdebase-workspace-libs.x86_64 0:4.2.95-5.fc12
kdm.x86_64 0:4.2.95-5.fc12
ksysguardd.x86_64 0:4.2.95-5.fc12
libgnomekbd.x86_64 0:2.27.2-3.fc12
libxklavier.x86_64 0:4.0-1.fc12
opencv.x86_64 0:1.1.0-0.1.pre1.fc12
xcb-util.x86_64 0:0.3.4-1.fc12

I have a lot of orphan packages, does removing those help this?
