Ah yess... there is a very good chance I did do that, because before there was an ebuild for jack-0.100.0+ I used to build it manually from source.
  Thank you very much and hopefully thats the problem.

You probably have multiple versions of jack installed. Both in /usr and in

Have you by any chance built jackd yourself (without specifying
--prefix=/usr to the "configure" script) and installed a version of jackd
from your distribution?

If yes, you should remove the one you don't want to use. Either remove the
package installed from your distribution via rpm or apt-get or whatever your
distro uses, or do a "make uninstall" from the jackd source directory you
built & installed jackd from.
