run-octave fails for default branch

[Ben Abbott]

John,

My build is ending with ...

Octave successfully built.  Now choose from the following:

   ./run-octave    - to run in place to test before installing
   make check      - to run the tests
   make install    - to install (PREFIX=/opt/octave/3.7)

Making all in doc

../../run-octave -f -q -H ./mk_doc_cache.m doc-cache ./macros.texi 
../../scripts/DOCSTRINGS ../../libinterp/DOCSTRINGS || { rm -f doc-cache; exit 
1; }
octave: failed to exec 
'/opt/octave/3.7/libexec/octave/4.1.0+/exec/x86_64-apple-darwin13.0.0/octave-gui'
make[3]: *** [doc-cache] Error 1

I'm in unfamiliar territory, but should the changeset below have been applied 
to the default branch?

        http://hg.savannah.gnu.org/hgweb/octave/rev/8d332da6694f

(with that applied to default, I'm able to run the cli).
