As expected, briefcase been added. But so has mobility==0.1.0 - which:

• isn't mentioned in the install log

• doesn't occur once in the briefcase sourcetree

• Isn't registered on PyPI

• Can't be uninstalled:

  (briefcase3.5) hammer:briefcase rkm$ pip uninstall mobility Not uninstalling mobility at /Users/rkm/projects/beeware/briefcase, outside environment /Users/rkm/.virtualenvs/briefcase3.5/bin/..

Some additional diagnostics to try:

• python -m site (prints resolved import system configuration details)
• python -c 'import pkg_resources; print(pkg_resources.get_distribution("mobility"))'

FWIW, I just tried your steps, but didn't get a mobility package installed.

My pip freeze (the initial error will be because I don't have git installed):

If it helps at all, on an Arch Linux machine, with Python 3.6, I end up with the environment below. Note that I had to manually request installation of ipython, since mkvirtualenv didn't do it for me automatically, as it appears to do for you. Given the "outside environment" error you're getting, I would assume it's an OSX-specific issue, maybe to do with the whole weird "Frameworks" thing.

Yes, Apple have done some weird path stuff; I am suspecting some quick investigation of actual paths will uncover it very quickly.
