Installation of mopidy-subsonic fails

I am new to mopidy, and raspberry pi for that matter. However, after going through the installation instructions for mopidy-subsonic, I cannot seem to get the backend extension to install. Below is the output I get when attempting to install via pip. Has anyone had success installing the subsonic backend for mopidy on raspbian? Any help would be greatly appreciated.

pi@raspberrypi:~ $ sudo pip install mopidy-subsonic

Not sure if that backend is maintained any more, but perhaps you can try opening a bug against it’s github repo if no one chimes in here?
