this is because there are no songs in the repo version. when you download FoF from sourceforge it comes with 3 songs. alternatively, you can put some songs in yourself in ~/.fretsonfire/songs/
but the FoF package for ubuntu gutsy is borked anyway (https://bugs.launchpad.net/ubuntu/+source/fretsonfire/+bug/160820). get the version off of sourceforge :)
