Compiling Octave with ATLAS

[David Parks]

I'm compiling Octave after having built the ATLAS libraries for my system.

 - How do I get octave to use the ATLAS libraries?
 - How do I *verify* that octave is actually using the ATLAS libraries?

This build process for Octave didn't seem to do it:

        sudo apt-get build-dep octave
        ./configure --with-lapack=/usr/local/atlas/lib/liblapack.a 
--with-blas=/usr/local/atlas/libptcblas.a
        make install

I can build and install Octave that way, but when I try to do large 
matrix multiplication I see only 1 core being used (my reason for 
building with ATLAS, and also the only way I currently know to test that 
ATLAS either IS or ISN'T linked properly).

I've tried all varients of --with-lapack that I can think of (pointing 
to /usr/local/atlas, /usr/local/atlas/lib, etc.), the documentation 
doesn't provide any concrete examples.
