I'm not sure what you are saying here: installing MacPorts Gtk does  
not cause its GHC to be installed, nor does it bind to it.

The way it works with Gnat, is that there is a GtkAda package which  
binds to Gtk, and the paths of this package must be set to whatever  
Gtk one is using. Using an external Gnat binding to MacPorts Gtk works  
just fine. As for the Intel Gtk package that binds to to Aqua, it is  
integrated with the Xcode GCC. So one must do some extra tweaking there.
