Thanks for your efforts. There can be the issue mentioned in the mail I linked previously. FLAC needs real libogg unless configured without but tremor provides both libogg and libvorbis functions but in incompatible manner. Linking flac + real ogg + tremor doesn't work for me. But maybe I have old version of something and latest versions work?

I checked it out from extras and see you started from debian version of debian directory but otherwise everything important is in. I will try similar route with 0.12. Thanks.
