However, you should still be able to use ctypes to interface with the
Fortran routines in scipy/linalg/flapack.so

While the CLAPACK is not always present, the Fortran-based LAPACK is.

This may however require some fiddling with the calling conventions.
So testing with multiple platforms will be needed, but perhaps you
are OK with doing that...
