We're trying to stay up to date on virtualenv releases so we don't fall too far behind and so we can leverage new features, such as wheels. This virtualenv release features upgrades to pip (1.4.1 to 1.5.4) and setuptools (0.9.8 to 2.2). These may fix bugs people are encountering in the wild. Tarball obtained from https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.11.4.tar.gz#md5=9accc2d3f0ec1da479ce2c3d1fdff06e. the egg-info directory was removed (consistent with previous virtualenv upgrades).
