[LAU] Installing zita-dpl1 on UbuntuStudio 18.04

FYI In the process of installing zita-dpl1 the install doc says to install libclxclient. To get libclxclient to build had to install libxft-dev (I installed libxtst-dev first but that didn't solve the X11/Xft/Xft.h no such file error) Could be just a omission on the part of Ubuntustudio 18.04... Once that worked I attempted to make zita-dpl1 and it couldn't find jack/jack.h. Attempted to install libjack-dev but I had to add libjack0 so libjack-dev would install. So now zita-dpl1 builds...Except now the jack is apparently gone. I use a script to setup my jack environment: #!/bin/bash set -x killall -9 jackd jackdbus jack_control ds alsa dps capture none dps playback none jack_control dps device hw:PCH jack_control dps rate 48000 jack_control dps nperiods 2 jack_control dps period 256 jack_control start <it goes on to create clients, etc> But when run jack_control no longer exists. So now I'm at a loss, I don't know how to reverse what I buggered up, and I don't know if I can add even more to fix it... :<( Any ideas? Mac
