Won't run on Ubuntu 16.0.4

I just came across this tool, and it looks awesome! I'm having some fun getting it going though.

I've just installed on my Ubuntu 16.0.4 server, using:

apt-get install glue-sprite

I didn't get any errors with the install. However, when I try and run it I do:

glue-sprite icons sprites
Traceback (most recent call last):

pkg_resources.ContextualVersionConflict: (Jinja2 2.8 (/usr/lib/python3/dist-packages), Requirement.parse('Jinja2<2.8,>=2.7'), {'glue'})

During handling of the above exception, another exception occurred:

pkg_resources.DistributionNotFound: The 'Jinja2<2.8,>=2.7' distribution was not found and is required by glue

Any suggestions?

sudo dpkg -l | grep jinj
ii  python3-jinja2                    2.8-1                               all          small but fast and easy to use stand-alone template engine

FWIW, I found out that I'm running an older (0.11.1) version of glue. It seems the current version is 0.13. How do I go about upgrading my install?

I'm not great with Python, so have never done this before (most stuff gets done via apt-get)

Thanks
