Sorry for being unclear. I meant the api that is exported to programs
like mplayer, vlc, gstreamer and apparently offered via
/usr/lib/libvorbis.so.0.

Excellent, can you please add this description to tremor source tree?
I remember spending at least three hours wondering this issue. I even
tried to patch tremor to export the same functions:

"I managed to link gstreamer0.10-plugins-bad against
libvorbisidec1. All I needed to do was to export all symbols that are
common to both libvorbisidec1.so and libvorbis.so so that
gstreamer0.10-plugins-bad is happy."
