Actually, np.dot does depend on the CBLAS interface to BLAS (_dotblas.c).

But the lapack methods in lapack_lite seems to use f2c'd code. I am not 
sure if they will use an optimized BLAS or just link to f2c's BLAS in 

If the intention is to avoid Fortran dependency in NumPy, I am not sure 
why this is better than a dependency on CBLAS and LAPACKE.
