you do not need to rebuild anything.

the only thing that you must do is to ensure that either:

    1) you remove the existing version
    2) you overwrite the existing version

how easy (1) is depends on your distribution. apt-based systems are
hard to use for (1).
for (2) you need to build from source with --prefix=/usr (assuming the
previous version was installed normally)

if you end up with 2 versions of JACK things will break. this is true
even if they are two different versions of the same "family" of JACK
