The order does not look right - I don't know the exact order (each
version of the MKL changes the libraries), but you should respect the
order as given in the MKL manual.

This suggests an error when passing argument to MKL - I believe your
version of MKL uses the gfortran ABI by default, and hardy uses g77 as
the default fortran compiler. You should either recompile everything
with gfortran, or regenerate the MKL interface libraries with g77 (as
indicated in the manual).

cheers,
