 From

 The short answer: Jack 1 and Jack 2 are equivalent implementations of the
 same protocol. Jack 2 was originally written to add multi-processor
 support and to rewrite the internals using C++. Programs compiled against
 Jack 1 will work with Jack 2 without recompile (and vice versa). Jack 2
 was originally planned to replace Jack 1, but this is no longer so and
 they are considered equivalent implementations. JACK is a C API, and so
 the C++ rewrite in Jack 2 only matters to the people who program/maintain
 jack.

 I'll update the port to 0.125 - Homebrew mentions they can't get jack2 to
 compile and i don't  see a reason to try unless someone provides a patch.
