karamba-news_panel still depends on the old x11-misc/superkaramba package, then when you perform a emerge -uavDt world the superkarmaba packages are blocking to each other. RDEPEND=">=x11-misc/superkaramba-0.21 [blocks B ] x11-misc/superkaramba (is blocking kde-base/superkaramba-3.5.0) [ebuild N ] x11-misc/superkaramba-0.36 USE="-arts -debug -doc +kdeenablefinal -xinerama +xmms" 1,466 kB
Fixed in cvs. Either x11-misc/superkaramba or kde-base/superkaramba should fill this dependency now. Thanks!
