Switching to the @Tim Edwards repo allowed make to work, but I can't install

Thank you for alerting me to this issue. I recently ran into an issue with some libraries having been deprecated in python3; switching to

shutils.copytree()

apparently surfaced an unexpected incompatibility. You can go back a couple of commits:

git checkout 1.0.508

which should fix the issue for now, while I update the repository with a fix.

Thank you for looking into it!
