Hi Ken, My Ubuntu 14.04 awailable both Python 2.7.7 and Python 3.4.0 versions.Me installed the python-louis, python3-louis, python-nose and python3-nose packages too to have possibility testing Python specific modules both Python2.7 and Python 3.4.
The 14.04 repo awailable Liblouis version is following: 2.5.3-2ubuntu1Because this version is little old, you need compiling from source with Liblouis to have possibility using the latest 2.6.0 version.
