You can run either.  If the DISPLAY variable is not set or if you pass
the '-nojvm' switch, matlab will start in command-line mode:

Warning: Unable to open display , MATLAB is starting without a display.
  You will not be able to display graphics on the screen.

I think it can if you have licensed the proper toolbox.  We did license
an MPI toolbox (IIRC), but I don't know if my users have actually
utilized it.

I don't think that you can just adjust the version.  It's a fairly
complex package with many patches that may no longer apply or may have
been included in the original distribution.  Your best bet is probably
to first see if you can build the pkgsrc version and if that's
sufficient.  If so, great.  If not, download the official tarball and
try to build it yourself.  If that works, see if you can package it.
Either way, post your results!


P.S.: X-post and followup-to tech-cluster.

If you are undertaking anything substantial, C is the only reasonable choice
of programming language.
