I was thinking Mesa and Xserver would have to stay even if new enough 
versions were released, because they actually call libwayland-*.

Without this they will be running Mesa and Xserver compiled for (and 
linked with?) the distributed libwayland-* rather than the one they may 
be trying to modify.

I am going to try to do a bisect and find out what version of Cairo 
fixes the xserver bug. But it should not be in the main instructions.
