error installing on mac M1 system about pyo

[RobertArbon]

hey - I've almost got this working.

I had to:

• reinstall homebrew and make sure all the dependencies are in the right place.
• clone the git repo and install using sudo python setup.py install --use-coreaudio --use-double
• fix the occaisional problem with it not finding header files by looking at the error message and making appropriate symbolic links to the various header file directories.

However - it's still not working but that's because of a bad link to an internal module which i'm tempted make a PR for. Not much help but it will get you closer to it working.

Actually - this still doesn't work. I'm at a loss.
