Hi Will

Thanks for your suggestion. Unfortunately `bundle doctor` did not mention
this library, and `gem pristine red-parquet` did not resolve the issue.

To be completely sure I removed the Ruby installation (with `rbenv
uninstall 3.0.3`) and installed it again, but unfortunately I still get the
same error.

Thanks
/Sten
