You are correct.

What live distribution and version was this? Booted on the same machine?

Yes, if I were on a wheezy system I would run the following

    sudo apt-get install libblas3 liblapack3
    sudo apt-get purge libatlas3-base libopenblas-base

The first command may do nothing if these libraries are already

The second apt-get command will tell you if any other packages need to
be uninstalled transitively because of removing libatlas3-base and
libopenblas-base. There are very few packages that have a hard
dependency on libopenblas-base.

I may be wrong, but I seem to remember that OpenBLAS 0.1 on wheezy was a
bit immature, and Octave recommended ATLAS at the time.
