Comment (by neverpanic):

 Somehow your jack port is in an inconsistent state. Please run
 {{{
 sudo port clean jack
 sudo port extract jack
 sudo port -st destroot jack
 }}}
 and attach the main.log. If that succeeded, you can also run
 {{{
 sudo port -s install --unrequested jack
 }}}
 to upgrade to the new jack version.
