--- Comment #3 from Michel Dänzer michel@daenzer.net --- That looks fine. Is there any chance that there are leftovers from your previous attempts at compiling Mesa or related components? E.g. check if
ldd /usr/lib/xorg/modules/libglamoregl.so
shows it picking up anything you compiled yourself, or just generally look for any leftovers.
