I have compiled OCaml 3.08 on Mac OS X. I have X11 installed, including 
the SDK with the header files and whatnot. When I configured the OCaml 
compilation, it did find my X installation and said it would be using 
it and installing the graphics module.

But:

$ ocamlmktop -o mytop graphics.cma
$ ./mytop
         Objective Caml version 3.08.0

# Graphics.open_graph "";;
Exception: Graphics.Graphic_failure "Cannot open display ".

I get the same exception when I try to put it in a file and compile and 
run it, whether compiled with the bytecode compiler or the native code 
compiler. So I know this isn't much to go on but I really am not sure 
what to do from here to get the Graphics to work so if anyone could 
point me in the right direction I would appreciate it.

Thanks.

Mike Benfield
