This breaks on OS X, which is UNIX but doesn't need X11 (although I do  
think it would be useful to be able to build the X11 port for OS X).  
The simple fix is to add "AND NOT MACOSX", but there may be a more  
clever way to indicate that we really need X11 support (maybe just  
force WANT_X11 to true on UNIX and give this message if WANT_X11 is  
true but X11 is not present; NEED_X11 might be a better name in that  
case).
