I am having some issues uninstalling python-librtmp.

I keep getting the error message No files were found to uninstall. when using pip to attempt to uninstall it.

To reproduce:

$ mkvirtualenv test --system-site-packages
Running virtualenv with interpreter /usr/bin/python2
New python executable in test/bin/python2

Let me know if you need more info (like installed-files.txt)

I'm not able to reproduce this here, using pip 6.1.1.

I wonder if it could have something to do with --system-site-packages, does it work without that?

[mic159]

Nope, I get the same without the --system-site-packages flag.

I have pip 1.5.6 on python 2.7.8 on ubuntu 14.10. But, I tested upgrading pip to 6.1.1 and it works. Something must be not backwards compatible.
