#Subject is currently not depending on these: x11-misc/util-macros x11-proto/videoproto x11-proto/scrnsaverproto x11-proto/resourceproto x11-proto/xf86driproto x11-proto/glproto x11-proto/dri2proto x11-proto/dri3proto x11-proto/presentproto x11-proto/xineramaproto Usually, other parts of the X11 stack pull these in, but during testing for XFCE stabilization (see blocker), I found that these were not DEP'd on, but configure complained about there absence (tested with 0.6.0, but I suspect the other versions need this too).
