I almost certainly had the 2013 edition last on my PATH when this problem occurred, and it reports version 4.7.4. I am having problems on the PLplot project that I work on and am fussing around there with a problem, and it is possible that I had the 2011 edition early on my path, and it reports version 4.5.3. But none of this makes sense because at all times the first two items in my path variable are /opt/local/bin:/opt/local/sbin so I don't see how a macports build would ever see a GNAT.

So the third step of his would be
sudo port install octave +gcc48
?
