Although kde4.2 contains kpilot, it seems that the ebuild is missing. So I sort of made my own. Reproducible: Always
Created attachment 183546 [details] kpilot 4.2 ebuild And here is the ebuild.
Added 4.2.1 version into the overlay. Will go to the tree next thursday/friday iirc
kpilot-4.2.1 is in tree now
