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
