When trying to run Kile (with USE flags: handbook pdf png -aqua -debug -kdeenablefina), the following message appears: "No editor component found. Please check your KDE installation." revdep-rebuild does not find any broken dependencies, nor does emerge -DuN world. After emerging kde-base/katepart-4.7.1, Kile starts smoothly. Reproducible: Always
Same problem here. kde-base/katepart solved it for me as well. Thanks for hint.
Fixed on kdelibs level, thanks.
