First and foremost, let me point out that current jack2 git compiles
fine on Debian unstable.

I didn't bother to try on Debian 7 (stable), but since you've compiled
libsndfile yourself, I have the gut feeling that it is more specific to
your local setup than a generic problem.

This is pretty clear. For some reasons, symbols from libflac were
referenced but later not linked against. This could either be due to
indirect linking or API mismatch (no idea if the FLAC API has changed
recently).

You can try this patch, but no guarantees (completely untested):
