This is not a build problem, but an execution problem.
Here is the message:
  The program 'lt-gtkglarea_demo' received an X Window System error.
  This probably reflects a bug in the program.
  The error was 'BadMatch (invalid parameter attributes)'.

I don't know exactly what causes it. Maybe a problem with xorg (I
switched recently), or with leftover libraries...
But lablGL itself works fine (with both Togl and glut)

(And no, I have no plan to run debian :-)
