I started building docs for a project of mine with readthedocs, and it was working great for a while, but now I get this crazy error:

Do I need to install setuptools somehow? Is that even possible? My module was using setuptools before and it was fine; what changed?
EDIT: This is on the public service, not on my localhost.
