           Summary: libGL cant find drivers if ProjectRoot is not /usr/X11R6
           Product: xorg
           Version: CVS_head
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Lib/GLX
        AssignedTo: xorg-bugzilla-noise at freedesktop.org

reason seems to be that DEFAULT_DRIVER_DIR is not defined anywhere.

================================================================
xc/lib/GL/glx/dri_glx.c:
/* this is normally defined in the Imakefile */
#define DEFAULT_DRIVER_DIR "/usr/X11R6/lib/modules/dri"
================================================================
$ grep -rl DEFAULT_DRIVER_DIR xc
xc/lib/GL/glx/dri_glx.c
