I have just spent a few hours getting past this error and this thread is a top google result, so I am adding my fix:
I had the same issue as Andrew. First, note that the tkf repo hasn't been updated for years, and the current emacs-ipython-notebook repo is millejoh's fork: https://github.com/millejoh/emacs-ipython-notebook. His is the current MELPA package, so under emacs 24, use package-list-packages and install "ein" to get emacs-ipython-notebook. Second, I had an old version of ipython. I uninstalled all the ipython on my system and reinstalled with pip: pip install ipython (giving me version 4.0.0). Then it worked.
