Sorry for having ignored your message for so long...

You are probably running IPython 0.11 and this code was written for
IPython 0.10.x.  Unfortunately some apis have changed and we haven't
implemented a backwards compatibility layer (it's not completely clear
we'll be able to do so completely, though I do want to try, I've
created an issue to track this

Your best option right now is to either uninstall 0.11.x altogether or
(better) to create a virtualenv in which you run 0.10.1 by default,
and run pygrads there.  That way, you can continue to use all the
improvements of 0.11.x while running pygrads on top of 0.10.x.
