Issue title: Binary nose package not properly registering the distutils entry point.
 Issue body: Currently, the ``nose-1.3.4-py27_0`` package contains ``lib/python2.7/site-packages/nose-1.3.4-py2.7.egg-info`` rather than the directory ``lib/python2.7/site-packages/nose-1.3.4.dist-info`` installed by ``pip install nose``.  This somehow does not properly register the ``distutils`` ``nosetest`` entry-point, breaking ``python setup.py nosetests`` as described in [this nose issue](https://github.com/nose-devs/nose/issues/873).

I'm not sure exactly what the problem is, but it would probably be solved by rebuilding the current package with a recent version of ``pip`` or ``setuptools``.

P.S. If this is not the correct place for submitting broken package issues, please let me know where the should go instead as it is not clear from the documentation.
 Comments: 
 Comment 0: This is also an issues with the ``flake8`` package for which ``python setup.py flake8`` fails with the binary installation of ``flake8``.
 Comment 1: A better place is https://github.com/continuumio/anaconda-issues.

 Comment 2: Okay.  I have migrated the issue.

 Comment 3: @asmeurer The migrated issue seems to be ignored.  Any suggestions on how to go about fixing this?
