* Cannot find $EPATCH_SOURCE! Value for $EPATCH_SOURCE is: * * /var/paludis/repositories/gnome/gnome-base/gnome-shell/files/gnome-shell-3.12-bluetooth-flag.patch * ( gnome-shell-3.12-bluetooth-flag.patch )
As a workaround copying gnome-shell-3.12-bluetooth-flag.patch from the files directory in gnome-shell-3.14 to the overlay gnome-shell/files directory and re-digesting the ebuild allows it to build.
The patch name in the overlay was different to the version in the tree. So I renamed the patch.
