Installing app_jack on asterisk 11

Thanks for your help. I am trying to install the app_jack.C application with Asterisk 11 on freeBSD 9.2. As I found in the menuselect, the application does not get installed automatically. It is not allowing me to choose the application by giving a XXX before the name of the application. on app_jack it says depends on jack(E) and resample(E).
I do not know what package I should install on this version of BSD.
Of course, the jack package called jackit is installed on the port by default.
