There is very likely something wrong with your sage install or something
incomplete about the upgrade or merge. Make sure to do
sage: hg_sage.pull()
etc. Try on sage.math using the system-wide sage and you'll see that
the above works. The error you get was, I think (maybe wrong), the
sort of thing
I had to fix in the sage library when updating the matplotlib spkg.
