What platform are you using? Does the BlendEqn example from 

   http://darcs.haskell.org/packages/GLUT/examples/RedBook/BlendEqn.hs

work? Is blending enabled at all? (blend $= Enabled) A short example program 
demonstrating the problem might help, too.

The "Yellow Book" is already on my desk... :-) I definitely intend to support 
GLSL in the OpenGL package, but if soon means "in the next few weeks", then 
the answer is "no". The GLSL API is not that small, so the implementation 
will very probably be done in a few iterations.
