I tests I did above were with hg id 4258750c76ed+

I'm using an old qscintilla.  Thus, after a pull/update (hg id cf84ea2ba2d3+) 
my build fails with ...

        src/m-editor/file-editor-tab.cc:30:34: fatal error: 
Qsci/qscilexeroctave.h: No such file or directory

When I have the time, I'll try to prepare a portfile for the latest qscintilla 
and build it via macports.  I tried using macports existing portfile with the 
most recent release of qscintilla, but that didn't work out.
