Thanks.  It mostly worked.  I still had the same basic error but the
path problem was fixed.  I deleted my old ipy_user_conf.py (as
instructed) and let %upgrade create a new one. It generated a diff the
first time it ran so I can review it to put back any important tweaks.

Would it be possible to add a config_file_version number setting in
the config file? Then ipython can check if the config file version is
compatible with the version running and otherwise give a clear warning
message and upgrade info (or patch it automatically in an ideal
world).  For less-experienced users the error specific error messages
don't identify the root cause or point to the handy %upgrade feature.

Thanks for the offer, but actually this might be a good opportunity
for me to look a little deeper into ipython starting with the pointers
you have mentioned.  I'll let you know if I get completely lost.
