That message is saying it can't find an X11 server for Tcltk to use.  If 
you do have X11 available, then just set the DISPLAY environment 
variable in the normal way; if you don't, then you're not going to be 
able to use that package on Unix.  (The Windows implementation is 
self-contained, so it should work there.)

I am having the same error message for Geneland, but I am implementing on a
Windows machine.
