Thanks Kevin. I'm cleaning up the shell scripts that we use on Travis-CI. There were several redundant uses of `pip install`, some of which were installing build requirements. The pull request is https://github.com/numpy/numpy/pull/15275, but I think the code can be further simplified. Does building with setup.py (instead of pip) use pyproject.toml?
