Pyreadstat

I can’t install pyreadstat. When I run `pip install pyreadstat`, I get this message:

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

Note: you may need to restart the kernel to use updated packages.`

How can I solve problem?

Start by reproducing `pip install pyreadstat` in Carnets and inspect the reported build path through `setup.py`, `pyreadstat/_readstat_parser.pyx`, `pyreadstat/_readstat_writer.pyx`, and `pyreadstat/pyreadstat.pyx`. Determine how this iOS environment is expected to handle the native extension and verify that installation completes without the `clang: command not found` failure.
