You need to install separately from source. I would also mention that
the BLAS portion of the vecLib framework that comes with your OS *is*
ATLAS, but it will be a little incomplete compared to self-built ATLAS
and LAPACK. Namely, the handful of LAPACK functions for which ATLAS
includes row-major versions and optimizes are missing. Possibly the
row-major version of the BLAS functions are also missing, but I haven't
checked.
