Comment:
An updated spkg is up at
http://sage.math.washington.edu/home/ghitza/gfan-0.4plus.spkg
Some fixes are needed in the Sage library because of the upgrade. I am
attaching a patch that deals with the most obvious one, but there are some
doctest failures left:

I can try to figure out what's happening, but Marshall is likely to be
better at it.
