This changeset includes three substantive changes to how the formula is
generated:
1. Rust has been added as a build-time dependency. This is the root
cause of the installation failure.
2. The major.minor version (`python3.9`of the python executable is used instead of
`python3`). This prevents the installation from inadvertently using the
system Python. This occurs because Homebrew only symlinks a `python3`
executable for the latest version. See Homebrew/homebrew-core/107517.
3. Adds `--allow-unsafe` to the `pip-compile` step. This is a noop
because we aren't pinning setuptools.
