Why? If you're using a Fedora/RedHat based OS then you should probably use the version from EPEL.  This is currently ansible-1.5.3-1.el6.noarch.  1.3.4 is rather an old release, so unless there is some bizarre reason for using that particular version then I would highly suggest using the latest release.

Yep, this happens when your SSL libraries don't match up with your python crypto libraries.

Ansible 1.3.4 is also very old and contains numerous things you don't want to deploy.

Grab the latest.

This bit me enough times that i eventually added a task for it in my playbook for creating new ansible controllers.

Its NOT pretty.  But it works and i've had no ill issues from it.
