pip uninstall does not remove symlinks

[greenpau]

When running the setup.py uninstall, the symlinks to ansible are getting removed properly:

# python setup.py uninstall
running uninstall
[INFO] deleted '/usr/lib/python2.7/site-packages/ndmtk'
[INFO] deleted '/usr/lib/python2.7/site-packages/ndmtk-0.1.9-py2.7.egg-info'

However, when using pip, the symlinks stay:

# pip uninstall ndmtk
Uninstalling ndmtk-0.1.9:
  Would remove:
    /usr/lib/python2.7/site-packages/ndmtk
    /usr/lib/python2.7/site-packages/ndmtk-0.1.9-py2.7.egg-info
Proceed (y/n)? y
  Successfully uninstalled ndmtk-0.1.9

# find /usr/lib/python2.7/site-packages | grep ndmtk
/usr/lib/python2.7/site-packages/ansible/plugins/action/ndmtk.py
/usr/lib/python2.7/site-packages/ansible/plugins/callback/ndmtk.py

The setup.py needs refactoring. Specifically, pip should remove the following files:

unlink /usr/lib/python2.7/site-packages/ansible/plugins/action/ndmtk.py
unlink /usr/lib/python2.7/site-packages/ansible/plugins/callback/ndmtk.py
rm -rf /usr/lib/python2.7/site-packages/ansible/plugins/action/ndmtk.pyc
rm -rf /usr/lib/python2.7/site-packages/ansible/plugins/callback/ndmtk.pyc
