Running parallel to Jockers’ attempts to “plot” texts via sentiment analysis, [Indico Data Solutions][] has released a Python package `plotlines` as well as a [Jupyter notebook][] of documentation and sample code.

Neither *indico* nor *plotlines* turned up in a `port search` so my next step was to try `pip`. My first attempt revealed that I was still using the Python 2.7 version of `pip`, and I needed both to get the version for Python 3.4 but also make sure it was the active version:

sudo port install py34-pip
sudo port select — pip pip34

And, then, to the matter at hand:

sudo pip install -U indicoio

*Success!*
