Use `pname` and `version`. Use my preferred indentation style. Use makeFlagsArray in preBuild instead of overriding configurePhase, per: https://github.com/jtojnar/nixpkgs-hammering/blob/master/explanations/explicit-phases.md Assert that lapack and blas are compatible regarding 64 bit indexing, do it near evaluation of preBuild, per jtojnar's explanation: https://github.com/NixOS/nixpkgs/pull/94892#discussion_r471110250 Use gpl3Plus, as gpl3 is unclear and deprecated.
