Ah, that explains it. Indeed it was the old pickles William has sitting in his directory. Mike asked me to churn out a bunch of lcalc files using the code you wrote over the summer that I was hoping to avoid doing on sage.math so as not to eat up too many resources. I'll ask Mike how pressing it is and see if it can wait until mod.math is updated to 3.3.alpha3 or if it will need to be run on sage.math in small pieces.
