[HOpenGL] Compiling hopengl apps?

[Hugh Perkins]

Started to play with hopengl.  It's pretty cool :-) Very easy to use, quite
cool :-)

Started to look at perf.  What interests me most is to see how fast we can
make vertex3f calls.  Basically, we're testing the speed of the haskell/c
boundary, where security(?) and marshalling are going to occur.

Yes, we can send the vertices to a vertexarray and not have to handle
vertex3f calls, but that's not what I want to measure ;-)

So, have a really rough and ready application that draws 45000 triangles a
frame, then measures the framerate.  Thats about 150,000 calls to vertex3f
per frame.

The application runs in Java, C#, and now Haskell.

Running in ghci, this runs at about 1.5 fps, really ballpark, havent checked
I'm really drawing the number of triangles I think I'm drawing, or settings
such as backface-culling or shademodel.  That's not too bad.

I'd like to compile to an executable to increase the framerate, but it's
giving me the following output:

What am I missing?
