You are using Fortran compiled libraries that are picked up by
numpy.core._dotblas and numpy.linalg.lapack_lite and so the
Fortran compiler must be used to link the relevant extension
modules. That's just a note for why sometimes fortran compiler
is needed to build numpy.

I'll look for your specific issue in a moment...
