HGL with GHC in Win32

[S.J.Thompson]

Can anyone help? I would like to run a program using the Haskell
Graphics Library under GHC on Windows. HGL is listed as a package 
(when ghc is asked about its packages) but not actually distributed 
as a package with ghc-5.02.3. On trying to remedy this, 

	- I am able to compile HGL by hand on windows, but on executing
	the HelloWorld.hs the program hangs: nothing happens.

	- HGL doesn't appear to compile on unix (solaris).

I'd be grateful for any feedback.

Thanks very much,

Simon Thompson
