I have updated to the latest master branch and built successfully. However, the moment I launch zeppelin, it dies with:

Could you click small gear button on top right corner of your notebook and see how your "Interpreter binding" look like? There should be "md" selected.

Starting today however for some reason all the notebooks refuse to run – they get an error.

It seems to have something to do with the list of interpreters. The above log was with the Zeppelin Tutorial notebook, running the very first paragraph. Any suggestions? Yen. P.S. I also checked the start up logs to make sure it picked up the configs correctly.
