Yes, we should fix this, but does your system not have an accelerated
BLAS+LAPACK library like ATLAS available?

Perhaps we should add a warning at the end of the configure step
saying something like

  WARNING: No accelerated BLAS+LAPACK library detected.  Using Fortran
  reference version instead.  For better performance, install ATLAS
  and re-run configure.
