portindex -f</nowiki>
Once indexed the local Octave port may be installed.
<nowiki>sudo port install octave-local sudo port install octave-devel @3.6.4+atlas+fltk+gcc47</nowiki>
The use of the {{Codeline|+atlas}} variant is encouraged as bugs exist for Apple's {{Codeline|accelerate}} framework in both MacOS 10.6 and 10.7. Octave's developers have included a fix for MacOS 10.6, but the fix does not work for MacOS 10.7. There is some commentary on this in various developers discussion forums. For example, see [ this Homebrew thread (Octave 3.4 fails on lion)], [ this R-Sig-Mac thread (R 2.13.1-patched, vecLib problem on Lion)], and [ the COIN-OR thread (Ipopt - problems on OS X 10.7 Lion)]. Use of Apple's {{Codeline|accelerate}} framework should also be avoided for {{Codeline|arpack}} and {{Codeline|qrupdate}}. To install the recommended variants, use the {{Codeline|port}} commands below.
As a precaution against unexpected problems and a bloated App bundle, using consistent variants for Octave and its dependents is suggested. For example, when using {{Codeline|+atlas}} make sure none of the dependents are using {{Codeline|+accelarate}}. Also, make sure no dependents are using the {{Codeline|+universal}} variant. Using the {{Codeline|+gcc47}} variant is also recommended as all of Octave's dependents have a {{Codeline|+gcc47}} variant. At the very least, following these suggestions will reduce the size of the bundle. The name of Octave's dependent ports may be determined by the command below.
<nowiki>port deps rdeps octave-local</nowiki>
The installed variants for each port may be determined by the command below. Be sure to replace "<portname>" with the name of the port.
