HOpenGL consists of two packages: OpenGL and GLUT, and the latter implies the former, so

ghc -package GLUT --make Hello.hs

Nope :( says GLUT is unknown package.

should work. To see which packages are installed, you can use

ghc-pkg -l

And surprizingly this gives the result rts, base, haskell98, network, haskell-src, readline, unix, lang, concurrent, posix, util, data, text, net, hssource which means neither HOpenGL, nor GLUT comes preinstalled in ghc-6.0.1 :(.
