Update to 1.8.4:

1.8.4 (2012-11-25)

    Updated distribute to 0.6.31. This fixes #359 (numpy install regression) on \ 
UTF-8 platforms, and provides a workaround on other platforms: \ 
PYTHONIOENCODING=utf8 pip install numpy.
    When installing virtualenv via curl, don't forget to filter out arguments \ 
the distribute setup script won't understand. Fixes #358.
    Added some more integration tests.

1.8.3 (2012-11-21)

    Fixed readline on OS X. Thanks minrk
    Updated distribute to 0.6.30 (improves our error reporting, plus new \ 
distribute features and fixes). Thanks Gabriel (g2p)
    Added compatibility with multiarch Python (Python 3.3 for example). Added an \ 
integration test. Thanks Gabriel (g2p)
    Added ability to install distribute from a user-provided egg, rather than \ 
the bundled sdist, for better speed. Thanks Paul Moore.
    Make the creation of lib64 symlink smarter about already-existing symlink, \ 
and more explicit about full paths. Fixes #334 and #330. Thanks Jeremy Orem.
    Give lib64 site-dir preference over lib on 64-bit systems, to avoid wrong \ 
32-bit compiles in the venv. Fixes #328. Thanks Damien Nozay.
    Fix a bug with prompt-handling in activate.csh in non-interactive csh \ 
shells. Fixes #332. Thanks Benjamin Root for report and patch.
    Make it possible to create a virtualenv from within a Python 3.3. pyvenv. \ 
Thanks Chris McDonough for the report.
    Add optional --setuptools option to be able to switch to it in case \ 
distribute is the default (like in Debian).
