Installing Jack() application

I seem to be unable to install the Jack application for Asterisk. When I try to select app_jack in menuselect, I see this - XXX app_jack and am unable to select it.
I am running the newest version 1.6.1.

Any Ideas?

Look at the Depends On line on menuselect.

Thanks for your response. I did notice the “Depends on” line after I posted.

Im getting the line “Depends on Jack[E], resample[E]”

Do you know if these are actual package names because I cannot seem to find them using APT?
