CELT is used by jack{1,2} for audio relay over the internet, and it is _very_ experimental (API can change between minor revisions). If installed and waf detects a package "celt" on the system, regardless of the version, jackd will build with it. However, waf configure lists no option to disable celt, so it is an upstream problem. jack2/jackmp depends on celt API version 0.5 OR 0.7, nothing lesser or greater. Even though it is a ">=" requirement, the build fails when 0.8 is installed, and so is an upstream issue once again. Version 0.8 is "NOT bit-stream compatible" with previous versions; applications need to rebase their code if a rebuild is not enough. Solution: celt-0.7 or no celt -- GPG/PGP ID: B42DDCAD
