===Install an Octave Port===
MacPorts' Octave port includes the non-GPL [ 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 [ epstool], [ pstoedit], and [ 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 . For macports 2.1.3, having the <code>xorg-libx11</code> as a dependency for Octave has been found to cause the <code>port mdmg octave-local ...</code> command to fail. The <code>xorg-libx11</code> dependency may be avoided by specifying <code>-x11+no_x11-docs</code> as variants and by dropping the dependence to <code>transfig</code> (which has <code>xpm</code> as a dependency and <code>xpm</code> depends upon several <code>xorg-*</code> ports.
A [[Prototype MacPorts PortFile|prototype portfile]] has been prepared, which does not depend upon METIS and does depend upon <code>epstool</code>, and <code>pstoedit</code> (there is no <code>transfig</code> dependency since it generates an <code>xorg-libx11</code> dependency). After [ creating a local portfile repository] an Octave portfile may be added to the local repository using the commands below.
