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 <code>print</code> 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 <code>epstool</code>, <code>pstoedit</code>
, and <code>transfig</code> has been prepared. After [http://guide.macports.org/chunked/development.local-repositories.html creating a local portfile repository] an Octave portfile may be added to the local repository using the commands below.
