Sure,

I tried to have a look at the homework of a friend. His university is
using Matlab. I'm working with nixos (www.nixos.org), a linux
distribution based on the pure package management system nix.
And the package which was present was pretty old. So I tried to just use
a newer tarball. For that homework speed didn't matter at all.
The distribution system only cares about i686 or x64_68. I didn't want
to spend much time on figuring out which packages to add as well..
But maybe I'll take the time to add a working atlas now as well because
it does take that long to compile octave with the atlas/blas fallback
library shipped with octave. In the end it might have been faster :)

Anyway I'd like to tell you that the dev version didn't work for me (1)
Don't spend time on that because of me. I'll try using atlas.

Sincerly
