Here it is.  Both OpenGL and GLUT are installed:
    Cabal-, GLUT-2.1.1, HUnit-1.1.1, OpenGL-2.2.1,
    QuickCheck-1.0.1, Win32-2.1.1, base-2.1.1, cgi-3001.1.1, fgl-5.4.1,
    filepath-1.0, (ghc-6.6.1), haskell-src-1.0.1, haskell98-1.0,
    html-1.0.1, mtl-1.0.1, network-2.0.1, parsec-2.0, regex-base-0.72,
    regex-compat-0.71, regex-posix-0.71, rts-1.0, stm-2.0,
    template-haskell-2.1, time-1.1.1, xhtml-3000.0.2

I tried using --make, but ghc said "could not find module GL"
