The big change in this release is it now uses the latest ncclient (0.4.1). You no longer need to use the Juniper private/fork version. The installation process has been streamlined so that it should all install nicely directly from PyPI using "pip install junos-eznc".
There are specific install instructions for Ubuntu 12.04 LTS at the top of this repo as well.
You may need to manually remove existing version of ncclient. If you run into any issues, please let us know and we'll work quickly to resolve.
Thank you!
