Toshio Kuratomi 0fe99f20d9 Emit an error message if six is not installed. ... dopy 0.3.7 makes use of six but doesn't list it as a requirement. This means that people installing with pip won't get six installed, leading to errors. Upstream released dopy-0.3.7a to address that but pip thinks that is an alpha release. pip does not install alpha releases by default so users aren't helped by that. This change makes ansible emit a good error message in this case. Fixes #4613		2016-12-08 11:25:19 -05:00
