Comment (by mojca):

 I didn't test the new commit yet, but in my case GraphicsMagick has been
 compiled with the standard/default clang compiler against `libstdc++`
 rather than with gcc (against gcc's own & incompatible `libstdc++`).

 If the dependency indeed has to be compiled with the same compiler, you
 are calling for bigger troubles by switching to `macports-gcc-6`.

 What role does GraphicsMagick play for Octave? Could it be disabled on
 older platforms if that is the likely source of troubles? Or is it
 absolutely necessary to do any plotting?
