I know that Tamas has some work in this area, and Cyrus Harmon's CLEM
meets some of the requirements.

Do you allow for F2CL'd LAPACK as an option?

The key question you havn't asked is what level of matrix operations
do you need?  BLAS1, 2, or 3?  (intuition:  vectors/matrices,
operations combining vectors with a matrix, matrix ops).
