You probably could make a creative use of the SAGE_ATLAS variable to point to your implementation of f77blas/cblas/lapack you may have to create links appropriately.

[sage-devel] Alternate Lapack Versions?
In my development, I'm attempting to parallelize some code. However, the bottleneck is a call to numpy.linalg.lapack_lite.zgesv, that is the point where numpy calls LAPACK to solve my complex system of linear equations. Ideally I'd like to parallelize this, and I know the ScaLAPACK has a parallel version, pzgesv. Is ScaLAPACK supported by Sage, or are there any plans to support it in the future? If not, I'll have to look for workarounds.
