ipython: ImportError: No module named jsonschema

I updated to IPython master this afternoon and I’m unable to run the IPython Notebook as a result. As the title of this issue suggests, I get an ImportError: No module named jsonschema.

I’m using Python 2.7.7, and am running the b6a05a573cac36cb394dd078f953e5a811ff283c commit.

The full Traceback is below.
