Having tried every single method of osx app building, all work w/ demo, none w/ deps

[kcrossen]

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>
