Hugs is very portable.  It works great on Solaris.
The source code is trivial to compile.  
>From memory, the instructions are:

  tar zxvf hugs.tgz
  cd hugs98/src/unix
  ./configure --prefix=$HOME/local --with-readline
  cd ..
  make install

Again, the code (for the Hugs Graphics Library and Hudak's 
 School of Expression library) is available and is portable.
Just download it and compile.  (http://haskell.org/graphics)

If you'd prefer to use raw Xlib, the graphics lib includes
 an Xlib library.

Other libraries are available - see haskell.org for details.
