   @alamb Actually this seems to be a known issue: https://github.com/PyO3/pyo3/issues/1741#issuecomment-958198336. Python doesn't seem to do the virtual environment path computation for embedded systems on Mac OS. A workaround is to extract that into `PYTHON_PATH` like so:
   
   ```
   export PYTHONPATH=$(python -c "import sys; print(sys.path[-1])")
   ```
   
   This is orthogonal to the original issue I had, which is that you must use a framework based Python install. That's default in Homebrew and Python.org installers, but not in pyenv.
   
   I have updated the error help to reflect these two issues.
