[SciPy-user] making an existing scipy installation use atlas libraries

The scipy installation instructions for Linux relating to atlas
(http://tinyurl.com/2kuwcy) appear to imply that one can force an existing
scipy installation that was built against netlib blas and lapack to take
advantage of subsequently installed atlas libraries by directing the
library loader to point to the atlas-provided libblas.so and
liblapack.so libraries rather than their netlib equivalents. Does this
approach provide inferior performance compared to building numpy/scipy
directly against atlas (i.e., such that the atlas objects are built
into the cblas/clapack modules)?
