Hi Sven,

Do you still maintain the OpenGL and GLUT packages?  Problem and solution
described below.

Thanks,

Cool; looks as if there were some Cabal-related changes, so that
bit mb fell on the floor (and non-Windows users aren't bitten by it.)
Package data for older GHCen have it, but in the ld-options field.

If you could fwd the mod to the maintainers, that'd be great.
