We used to run “ipython notebook” to get the notebook version of IPython, but this has been removed and we are supposed to use a new program called Jupyter. I installed what I guessed is required to use Jupyter with port install py34-jupyter and py34-ipykernel.

Looks like we need a `port select` group for the jupyter binaries. As
for you issue, it appears to be this bug:

https://github.com/jupyter/notebook/issues/448

which looks like the next release will fix.

For now, you can run jupyter-notebook-3.4 (assuming py34-notebook is
installed).

Correct, please don't do that.
