How can you install pip from here?

As we all know, pip requires setuptools but when trying to install setuptools on a fresh new CentOS 6.8 with Python 2.7 installed exactly as in this script, it raises that there are some core python packages missing which leads to a circular dependency error.
Package "setuptools" wants "six", "six" wants "packaging", "packaging" wants "pyparser" and "pyparser" wants "setuptools".

Thank you.

Maybe you could use the following commands for getting setup-tools and pip installed

install setup tools

curl https://bitbucket.org/pypa/setuptools/downloads/ez_setup.py | python2.7 -

install pip

curl https://bootstrap.pypa.io/get-pip.py | python2.7 -
