bad interpreter error with python-subunit 1.0.0 installed by pip

[Yi Ming Yin]

With the latest python-subunit 1.0.0, if I used pip install python-subunit. 2 installed scripts under /usr/bin/ will have bad interpreter set at the first line with #!:

/usr/bin/subunit2junitxml:

#!/home/robertc/work/nova/.venv/bin/python
# subunit: extensions to python unittest to get test results from subprocesses.

However, if I download the source code from pypi, all the interpreter has been set correctly to #!/usr/bin/env python.

I noticed that these bad scripts are included in pypi python wheel file:
https://pypi.python.org/packages/2.7/p/python-subunit/python_subunit-1.0.0-py2.py3-none-any.whl#md5=57780d8cf11e9968ae78fd5ea32397af

I've removed the wheel, will dig into why that happened later.
