Unable to load jar in Python virtualenv

[GoogleCodeExporter]

It's best practice to install Python projects into virtual environments. So, 
adapting your installation instructions, I did:

    sudo apt-get install -y python2.7 python-wxgtk2.8 openjdk-7-jdk gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly gstreamer-tools sox mplayer python-setuptools
    virtualenv --system-site-packages .env
    . .env/bin/activate
    pip install MplayerCtrl
    svn checkout http://voiceid.googlecode.com/svn/trunk voiceid
    cd voiceid
    python setup.py install

This installs fine, but when I attempt to run the `vid` command, I received the 
error:

    IOError: File /usr/local/myproject/.env/local/share/voiceid/LIUM_SpkDiarization-4.7.jar doesn't exist or not correctly created

This is because CONFIGURATION.LIUM_JAR is hardcoded to look in /local/share, 
but virtualenv creates a `local/` and a `share/`, but no `local/share`. I fixed 
this by symlinking `share/` into `local/`, but it might be easier to modify 
your code to check both locations.
