hehe ;)

Dodgy indeed

So, for comparison, I did an ldd on RhythmBox. It *actively* uses the 
gnome libraries, the canvas, gnome-vfs, libxml, gal, gstreamer, 
libcdaudio and the ogg/vorbis libs. And I will soon add PonG to the 
list... And it statically links to mplib. I'm also thinking of moving 
libcdaudio inside the repository, and link statically to it.

In the end, it's pretty awful...
