Requirements for Ansible are extremely minimal.
Ansible is written for Python 2.6. If you are running Python 2.5 on an "Enterprise Linux" variant,
your distribution can easily install 2.6 (see instructions in the next section). Newer versions
of Linux and OS X should already have 2.6.

Ansible can be installed via Pip, but when you do so, it will ask to install other dependencies used for
optional modes::
