Having `easy_install` available (or something similar) is likely an ongoing need for at least one reason. If a user wants their system to stay on the latest/upstream version of pip, one sensible way of doing this is to install the `python-setuptools` package and use `easy_install` to install `pip` straight from PyPi, and then from that point forward use `pip install -U pip` to keep it up to date.
