Hey, I found your changes, do you mind updating the "import pkg_resources" too? This way we have all the patches in the same repository. The function files() apparently is the replacement. I think we will need to use this zodburi version toohttps://github.com/Pylons/zodburi/tree/modernize-python-versions.

Edit: I made a commit on top of your changesscmanjarrez@236ec07

I'd be interested to see a permanent fix for this if possible.
