when doing world update while compiling x11-libs/gtk+-2.18.6 I get this error: In file included from gdkdisplay-x11.c:40: gdkinputprivate.h:38:35: error: X11/extensions/XInput.h: No such file or directory In file included from gdkdisplay-x11.c:40: gdkinputprivate.h:79: error: expected specifier-qualifier-list before 'XDevice' gdkinputprivate.h:175: error: expected declaration specifiers or '...' before 'XEventClass' make[4]: *** [gdkdisplay-x11.lo] Error 1 Which is virtually identical to the bug at the URL above.

Apparently it should be.
