Tested against octave-2.9.6.  No backward compatibility to 2.1.xx.  Use
an older release of octave-forge instead.

The usual build instructions apply: 

  ./configure; make; make check; make install
  
Note that some tests will fail because of known bugs or missing
features.  This should be indicated in the tests themselves.
