if the message says that you need X11 installed then you do not have X11 installed. a lot of OS X user seem to make the “mistake” of finding the first thing in Apple’s software install/update tool that has the words “X11” in it and install that. This is not X11, its full name is the X11 SDK, and its necessary if you want to build Ardour from source, but is NOT necessary in order to run a prebuilt version of Ardour. You MUST install the real X11 from the system disk that came with your machine, as specified on the OS X requirements page.

we added that message precisely because so many people have made this (or a similar) mistake.
