===Install an Octave Port===
   −
For the purpose of creating an App bundle using MacPorts, an Octave port must be installed. A standard MacPorts port or a local port may be used. For a local portfile it is first required that a [http://guide.macports.org/chunked/development.local-repositories.html local portfile repository be created] and the local portfile placed there.
+
MacPorts' Octave port includes the non-GPL [http://glaros.dtc.umn.edu/gkhome/views/metis METIS]. To avoid license violations do not bundle Metis with Octave and then distribute to others. In order to eliminate the Metis dependency, a local portfile may be used, and edited to remove metis. A second motivation to use a local portfile is that the portfiles for the 3.4.x and 3.6.x series did not include all dependencies for the {{Codeline|<nowiki>print</nowiki>}} feature.  The missing dependencies are [http://www.macports.org/ports.php?by=name&substr=epstool epstool], [http://www.macports.org/ports.php?by=name&substr=pstoedit pstoedit], and [http://www.macports.org/ports.php?by=name&substr=transfig transfig].  A third motivation for a local portfile is to provide additional flexibility in resolving problems with creating an Octave DMG using the <code>port mdmg ...</code> command .

A [[Prototype MacPorts PortFile|prototype portfile]] which does not depend upon METIS and does depend upon epstool, pstoedit, and transfig has been prepared.
