python-pip-whl 1.5.6-3 (amd64 binary) in ubuntu vivid

 pip is a replacement for easy_install, and is intended to be an improved
 Python package installer. It integrates with virtualenv, doesn't do partial
 installs, can save package state for replaying, can install from non-egg
 sources, and can install from version control repositories.
 .
 This is the support package for the PEP 427 wheel version of the package,
 required for using pip inside a virtual environment.
