Created attachment 455410 [details] Emerge dump As it says in the failing compilation, the newer version of xfce4-settings needs exo-11 or higher. As I already updated exo manually, my build log is not relevant anymore. Therefore I only include what Eemerge dumped for me. This states cleary with the failing configuration step that the above is the problem.
