Leider ist das offizielle Portage nicht immer up2date (sci-mathematics/octave-2.1.73-r2) und aus diesem Grund hier nun der einfachste Weg zu octave 2.9 unter Gentoo.

  1. # emerge layman
  2. # layman -a science
  3. # echo “source /usr/portage/local/layman/make.conf” » /etc/make.conf
  4. # emerge -av octave

These are the packages that would be merged, in order:
