Octave’s GUI did not work after MacPorts-Update

After the last MacPorts update (v2.3.4), Octave’s GUI did not run anymore. The reason was the wrong gcc variant.

I installed Octave with the gcc49 variant on MacPorts 2.3.3:

sudo port install octave +atlas+gcc49+glgui+gui+java

Octave – at least the GUI – depend now on GCC 5. The follwing solves the problem:

sudo port install octave +atlas-gcc49+gcc5+glgui+gui+java

This problem should not appear on a new installation of Octave because it is compiled with +gcc5 by default.

My environment: Mac OS X 10.9 (Mavericks), MacPorts 2.3.4, Octave 3.8.2
