Thanks for the report, I manage to install Zbarlight on Ubuntu Trusty using the commands below. The only things that differ from your setup is the Python version (2.7.6 vs 2.7.12) and maybe the Setuptools version. Zbarlight requires Setuptools >= 30.3, could you check that this requirement is meet ?

(host) $ docker run --rm -ti ubuntu:14.04  # run an instance of Ubuntu Trusty

(ubuntu) # apt install python python-dev libzbar-dev python-virtualenv
(ubuntu) # adduser --disabled-password --gecos ",,," zb
(ubuntu) # su -l zb
(ubuntu) $ virtualenv venv
(ubuntu) $ . ./venv/bin/activate

Unfortunately it's not on docker so not sure what in my environment got 'polluted'.

(venv) $ pip show setuptools | grep Version

Version: 39.1.0
