I can't tell if this is a bug in MacPorts, or if I have simply
misconfigured something.
When I start up `ipython notebook`, with python-2.7 as my selected
python, everything works fine, but I get a complaint echoed to the
shell:
```
[TerminalIPythonApp] WARNING | Subcommand `ipython notebook` is
deprecated and will be removed in future versions.
[TerminalIPythonApp] WARNING | You likely want to use `jupyter notebook`
in the future
```
All works well, nevertheless, and I'm happy, except for the crabby note
from ipython.
But, if I try to do what the message says, and run `jupyter notebook`
instead, I get an error:
```
$ jupyter-2.7 notebook
Traceback (most recent call last):

```
So I was wondering if there's an issue with jupyter or, if somehow I've
gotten things misconfigured.
Thanks
