commit 7b9c543e7210c7da204871c31a160e79d3a949b6: Bug 15664: xau & xdmcp not needed in x11.pc dependencies when built with xcb .... Short of it: dependency should be changed to !xcb ( x11-libs/libXau x11-libs/libXdmcp ) It's of course cosmetic, as the dependency simply becomes indirect (via libxcb). And yes, I do see, that ebuild for 1.2.1 is not even on the overlay (though it's been out for nearly a month) - it was probably missed during xorg-server upgrade rush.
Fixed and bumped in the overlay. Thanks
