This looks like an ATLAS configuration problem. I've seen similar
errors but I can't reproduce this particular one.

First try this, in a terminal:

    sudo update-alternatives --auto liblapack.so.3gf
    sudo update-alternatives --auto libblas.so.3gf

And see if Octave works now. If not, you can completely remove ATLAS
to use Octave with the standard reference BLAS and LAPACK libraries.
Either search for libatlas3gf-base in the software center or

    sudo apt-get purge libatlas3gf-base

And see if that resolves it.
