"Thomas Kirste" <kirste at acm.org> recently provided us with a fixed
copy of Hugs and a prebuilt copy of the HGL.  I have put a copy at:

  http://www.reid-consulting-uk.ltd.uk/downloads/HGL.MacOSX.tgz

Those that prefer source code should replace hugs98/src/machdep.c with

  http://www.reid-consulting-uk.ltd.uk/downloads/machdep.c

and replace graphics-2.0.4/lib/x11/Makefile with 

  http://www.reid-consulting-uk.ltd.uk/downloads/Makefile

These changes are also in the CVS repository but we're making changes
to how the foreign function interface works at the moment and, whilst
it should still work fine with the HGL, this hasn't been checked so
I'm playing safe and sending out Thomas' code exactly as he sent it.

Installation:

(1) Make a backup of all files you replace / delete
    during installation

The original HGL distribution including terms of license
