Yep, that's the unfortunatly quite non-descriptive error you'll get when
a module exports a binding it does not define.

Indeed `assert' is missing from Guile ATM, but I've submitted a patch a
while ago that fixes that (among other things):

I hope that someone gives that patch a review soon (*hint* *hint*)...
