OK, so the package needs some more work to use the fortran compiler 
that pkgsrc gives it rather than its idea of the best from what it 
can find.

The package is assuming the attached fixes to the lapack and blas 
packages, that I haven't got around to committing yet.

Presumably octave is linking in such a way that it pulls in the 
fortran runtime libraries itself whereas numpy doesn't, certainly 
thats what happens in the case of other users of lapack and blas 
(such as R).
