Log message:
Update to latest release, 1.11. From doc/news.rst:

1.11 (2014-01-02)
~~~~~~~~~~~~~~~~~

* **BACKWARDS INCOMPATIBLE** Switched to using wheels for the bundled copies of
  setuptools and pip. Using sdists is no longer supported - users supplying
  their own versions of pip/setuptools will need to provide wheels.
* **BACKWARDS INCOMPATIBLE** Modified the handling of ``--extra-search-dirs``.
  This option now works like pip's ``--find-links`` option, in that it adds
  extra directories to search for compatible wheels for pip and setuptools.
  The actual wheel selected is chosen based on version and compatibility, using
  the same algorithm as ``pip install setuptools``.
* Upgraded pip to v1.5
* Upgraded setuptools to v1.4
