kde-base/plasma-workspace:4.3 depends on kde-base/kde-menu-icons:4.3, which is missing from portage ATM. Is it on the way or has it been forgotten? Reproducible: Always
it wants kdebase-menu-icons not kde-menu-icons. And the package is defiently in main tree.
If you have some dependency issues with update, try to join #gentoo-kde on freenode.net. We will try to help you with it there tho :] Cheers
Oh I see. Thanks a lot and sorry for the noise.
