This worked like a charm for me with Ubuntu Mate 16.04 & 18.04. thank you!
No problem. I was just having a hell of time of it, and I thought, "I should write this down in case it actually works." Some of the info I cribbed from the litecoin source compile instructions. When configure ran with no errors I knew I was cooking with gas. When make finished with no errors I knew that gas was propane.
