Comment 3 for bug 1497006

I also seem to have similar issues on py3 unit tests jobs (was running on rax?)

it seems there's some failure due to six is not available in the environment when setuptools tries to use it, which is also present in the logs of jobs described above (ansible was not installed due to the same failure - http://logs.openstack.org/24/469624/2/check/gate-tempest-dsvm-ironic-pxe_ipmitool-postgres-ubuntu-xenial-nv/ba57cc8/console.html#_2017-06-01_06_45_13_483721

and a new release of setuptools 36 was just pushed today (June 1, 2017). coincidence? :)
