text: Title: Shebang on vba_extract.py set incorrectly in wheel
  Body: The shebang at the beginning of vba_extract.py is set to `#!/Users/John/.pythonbrew/pythons/Python-2.7.2/bin/python` which is specific to a particular installation. It should probably be changed to just `#!python`.
  
  Example which demonstrates the problem:
  
  ``` shell
  $ vba_extract.py
  bash: /usr/local/bin/vba_extract.py: /Users/John/.pythonbrew/pythons/Python-2.7.2/bin/python: bad interpreter: No such file or directory
  ```
