I'm sorry that the build is hard to do. The scipy webpage has some
information on how to build,
https://docs.scipy.org/doc/scipy-1.10.1/dev/dev_quickstart.html. You
shouldn't have to rebuild time after time, you should just be able to run
`python dev.py test`, tweak, `python dev.py test` without having to do
anything else. In this circumstance I might suggest removing the build and
build-install directories and just running `python dev.py test` multiple
times. Unless you want to specify specific BLAS libraries you shouldn't
have to use any flags. If you're on Linux, you can just install system BLAS.
