Disregard PR linkage, install.md is about build deps of the tower server, and these seems to be about adding a dependency to hosts Ansible will be ran against (as far as I understand).

CC @AlanCoding, you probably know what the thing to do here would be.

[AlanCoding]

An upstream exists for the backport code - and here is what we're talking about https://github.com/ansible/ansible-inventory-backport/blob/master/backport.py#L323

We should prefer to use something more durable along the lines of python's disutils.find to find the Ansible location.

Good bug, thanks for raising it.
