Install of pinned av fails on Big Sur 11.7.10

The problem

When following the instructions to install I encountered the following error:

Building wheels for collected packages: av
  Building wheel for av (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

@systemcrash: What do you think?

[systemcrash]

This definitely looks like a 'them' problem and not an 'us' problem.

[AmitDeshwar]

I tried installing av without the pinned version. The program ran, but it wasn't discoverable by the other machines on the network. Could this be explained by the av version?

[systemcrash]

No. Discovery is at a start due to mdns.

[AmitDeshwar]

Okay, looks like my problem is elsewhere then! Maybe the version pin isn't necessary?

[systemcrash]

The version pin prevents loads of problems by retaining known good versions. Everyone is free to try other versions if they know how.
