Emit an error message if six is not installed.

Browse source 
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
