Problems installing on Ubuntu 16.04

I have been trying to install this on Ubuntu 16.04 with no success. I've have carefully followed the instructions in the readme and as indicated here on GitHub. The following is my setup and installation.

PART 1 -- ENVIRONMENT

I have a moderately new (Feb 2017) installation of Ubuntu 16.04. Specifically:

computer platform = Linux-4.4.0-75-generic-x86_64-with-Ubuntu-16.04-xenial
python version = 2.7.12
numpy version = 1.12.1
scipy version = 0.19.0
(py)ephem version = 3.7.6.0
matplotlib version = 2.0.0
h5py version = 2.6.0
PIL version = 1.1.7

PART 2 -- INSTALLATION

The following are my installation steps. Python 2.7 (incl. numpy, scipy, etc.) were already installed as indicated above.

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:kernsuite/kern-1
sudo apt-add-repository multiverse
sudo apt-add-repository restricted
sudo apt-get update
sudo apt-get install python-casacore
sudo -H pip install git+https://github.com/sabourke/lofarstationdata

All of these ran without any indication of error.

PART 3 -- TESTING

First I check that the executable is present.

% which lofar-station-ms
/usr/local/bin/lofar-station-ms

Then I try running the "help" option, as indicated in the documentation. This is where it starts to fail.

% lofar-station-ms --help
Traceback (most recent call last):

PART 4 -- HELP?

Any suggestions on additional packages that might be needed or any configurations steps that could tried? If possible, could these be added to (or clarified in) the documentation. Thanks.
