#Subject is currently not depending on these:
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).
*** Bug 560970 has been marked as a duplicate of this bug. ***
With x11-base/xorg-proto it is not possible for this to occur anymore.
