Demo apps from gallery w/o dependencies all work w/ various build methods.
No documented build method works (as documented) for an osx app w/ dependencies:
urllib3, botocore, boto3.
The same osx app's python script w/ the above dependencies does work via drag/drop onto Kivy.app provided that the dependencies have been pre-pip-ed using
pip install <dependency> -t <path to kivy.app venv>
