Dear Maintainer,

When creating a virtual environment with virtualenv, the dependent
..whl files are copied into <venv>/lib/python-wheels/*.whl.  This
allows pip inside such venvs to work.

However, inside pyvenv created venvs, there are no wheels in
<venv>/lib/python-wheels so pip inside pyvenv created venvs does not
work:

% pyvenv-3.4 /tmp/aa
% source /tmp/aa/bin/activate
(aa) @chemistry[~:1003]% pip install nose2
Traceback (most recent call last):
  File "/tmp/aa/bin/pip", line 7, in <module>
      from pip import main
  File "/tmp/aa/lib/python3.4/site-packages/pip/__init__.py", line 59, in <module>
    from pip.log import logger
  File "/tmp/aa/lib/python3.4/site-packages/pip/log.py", line 9, in <module>
    import colorama, pkg_resources
ImportError: No module named 'colorama'

% find /tmp/aa -name \*.whl | wc -l
0
