I see a further difficulty here. The pygments module could be installed as a python 2 or python 3 module. The right python version to use is determined by the used pygmentize command. So, if we are running python 2 and don't find the pygments module, it is not an indication that it is not available. Conversely if we are running python 3 and pygments is installed as a python 2 module. Maybe, the only sensible thing to do is checking for a pygmentize command and, if not found, warn the user but don't disable the widget. -- Enrico
