Ubuntu, Claymore 12.4 and AMD Display Library

(Newbie Q) I'm runing Ubuntu 16.04 w/Claymore, 6x RX 480 8G, and most current AMD drivers. When I start Claymore it said something like unable to access ADL which is AMD Display Library. I'm thinking Claymore uses this to control the cards various activities. How do you install ADL in Ununtu?

TIA
