[IPython-User] update just ipython within an enthought python distribution on mac

[Jonathan March]

It's a permissions failure. The command (and most other enpkg commands on
Mac) should be sudo'd (or chown the Python2.7 sub-tree, though I haven't
tried that myself.)

That is a misleading error message, since fixed in master but not yet in
repo. Sorry!
