Dotaz: Kompilace gnome-media 2.12

[filbar]

Při kompilaci gnome-media jsem narazil na tuto chybu:

Pátral jsem také na mailing listu GNOME, ale tam se sice dvakrát objevila podobná chyba, ale nikdo na ní neodpověděl. Nevíte co mám špatně?Gstreamer mám nainstalovaný.
Co vlastně znamená chyba

undefined reference

?

Na otázku zatím nikdo bohužel neodpověděl.
