Yes you can install without ATLAS. And BLAS and LAPACK were found so you
should be fine. Did you have an actual problem or are you asking out of
curiosity?

Numpy does not contain any Fortran code, Scipy does. But that warning
doesn't mean you have a problem - a number of compilers are checked and the
first one that's found is used.

Please also have a look at the RHEL section on
http://www.scipy.org/Installing_SciPy/Linux.

Cheers,
Ralf
