Quote from INSTALL.txt:
"""
BLAS sources shipped with LAPACK are incomplete
-----------------------------------------------
Some distributions (e.g. Redhat Linux 7.1) provide BLAS libraries that
are built from such incomplete sources and therefore cause import
errors like
::

   ImportError: .../fblas.so: undefined symbol: srotmg_

Fix:
   Use ATLAS or the official release of BLAS libraries.
