installing Doorstop on macOS (for RTEMS use)

[Andrew Butterfield]

Hi Chris,

  I got around to doing a doorstop install that does not rely on homebrew,
using the python.org <http://python.org/> distribution for 3.8

Everything worked fine - python3 is installed in /Library just like the OS X native python 2.7
Doorstop runs just fine too.

Regards, Andrew
