Disclaimer: I've never cast numpy, and have no familiarity with it, so
take whatever I say next with a grain of salt.
That having been said, this smells like numpy will pull in atlas as an
optional dependency if it finds it in the system (unless of course
Ladislav had previously cast numpy with atlas, and then dispelled atlas
while leaving numpy, but I'm assuming that's not the case here).
Additionally, the following is taken from the numpy website:

Linear Algebra libraries
Various SciPy packages do linear algebra computations using the LAPACK
routines. SciPy's setup.py scripts can use number of different LAPACK
library setups, including
optimized LAPACK libraries such as ATLAS or the Accelerate/vecLib
framework on OS X. The following notes give detailed information on how
to prepare the build
environment so that SciPy's setup.py scripts can use whatever LAPACK
library setup one has.
NumPy does not require any external linear algebra libraries to be
installed. However, if these are available, NumPy's setup script can
detect them and use them for
building. If you do not plan to build the full SciPy then you can skip
this section.
