In file included from /usr/local/include/xorg/randrstr.h:46:0,
                 from ../../src/radeon_probe.h:43,
                 from ../../src/radeon_misc.c:27:
/usr/local/include/xorg/servermd.h:50:24: fatal error: dix-config.h: No such file or directory
 #include "dix-config.h"
                        ^
