MMTK picks the best diagonalization routine it can find, checking for
NumPy and SciPy modules and checking for PyLAPACK. It always ends up
using some LAPACK routine for eigenvectors of a symmetric matrix.

It is perfectly possible to implement DIMB as an alternative, but
right now there is no DIMB implementation for MMTK.
