We get this error last week on our Rhel7 server.

This fix makes sense for the setup.py file in order for the modules to be correctly installed. I will merge this pull request. Thanks for submitting it.

This isn't directly applicable to your commit, but it's worth stating here for future reference.

Using /usr/bin/env is not the recommended approach within modules themselves. For modules, the shebang line of the modules should be set to #!/usr/bin/python and the ansible_python_interpreter variable should be used as needed to specify an non-default Python2 location.

See: this reference or
that reference

The modules don't currently comply with this recommendation. They currently have /usr/bin/env in the shebang line instead. We should probably address that under a separate issue.
