Unfortunately not, because the precompiled binary is not dynamically linked
with BLAS. As a matter of policy, I only link with libraries that are provided
on the main Red Hat distribution. The blas library only appeared in the main
distribution in release 7.1 (Previously it was on the Powertools CD).
