If you have two versions of JACK installed it will cause problems.
Ardour expects to find libjack.so in /usr/lib and will use that instead of
the one in /usr/local/lib. You can make it use the correct one by
removing the packaged version and putting a symlink from
/usr/lib/libjack.so to /usr/local/lib/libjack.so:

ln -s /usr/local/lib/libjack.so /usr/lib/libjack.so
