Created attachment 381602 [details] sddm-9999-consolekit.patch.out I wanted to install sddm with USE="consolekit", which failed with mentioned patch.
Fixed, please, test. Anyway it is recommended to use sddm with systemd, not with consolekit, see https://bugs.gentoo.org/show_bug.cgi?id=511484 If you do not like systemd you have lots of dysplay managers, that have support for consolekit.
