As far as I can tell, numpy requires a fortran compiler. Not installing
one is what leads to errors in #43321. Any port touching computation
(i.e. blas/lapack) almost certainly will have to install some kind of
fortran compiler.

I think this kind of dependency is unavoidable if we want to maintain
consistency and reproducibility. :-/
