Comment 4 for bug 493269

I don't believe that using the Debian/Ubuntu name it's a good idea. There are people on BSD and ARCH Linux using GTG, and I'm pretty sure that the name changes.
But, most important of all, either we hand-write in the config file the name of the corresponding module, or I don't see an easy way to get it in an automated fashion. Calling apt-file search? Not a good idea.
We could just write something else instead of "missing dependencies", like "missing python dependencies".
