As discussed on IRC: Unfortunately OS X Yosemite ships with a woefully out of date OpenSSL, LDAP Lib, etc. Some of these are not easy to replace with homebrew (some are). These out of date libs are usually left only for compatibility while people move to Apple’s specific alternative libs.

Recently I ran into a couple issues with python packages that would not work without updating the setup.py (and not in a friendly way that should be done for up-stream, I think LDAP was the culprit this time). This headache made the packages unsuitable for installation in a venv via tox. As of before the 2014 holidays Keystone (and it’s Unit tests) are no longer supported on OS X. Your milage may vary with OS X older than Yosemite.

I recommend using Linux in a VM if you’re on OS X. Alternatively a bootcamp install of Linux would also work on most Apple laptops / machines.

Sorry for the bad news in this case.
