How to install the gnat GPS for Mac using x11?

Question

I was in a conference today, and the person talking had a Mac OS X system with the Gnat GPS IDE installed, but the app name in the top tollbar was "X11".

I would like to have GNAT GPS IDE on my Mac. I dont know how to install it with X11? Any help?

Currently I code in the "Text Editor" app and compile it through terminal using the gnatmake command.

Up to Lion, X11 came with the OS (I think it may have been an optional install). In Mountain Lion, Apple no longer provide an official X11; however, when I started GPS for the first time on this new machine - as above - I was told how to install XQuartz. It Just Worked.
