Awesome, thanks for reporting back!

Thank you SO much for responding @ddelange. I still can't get the postal scrubbing to work in scrubadub.py, but that's a problem for another day. It's not because it can't find libpostal, at least. The likelihood of there being postal data in this repository is nil, so I'm going to leave it for now.
