Trouble of installing Omniscidb on Mac

I clone the Omnisci source code from GitHub and follow the steps on the Omnisci website, running the script on terminal which help install everything needed. But my installation stuck after I’ve installed all the dependencies. And it stuck at the steps of build_pin_dep boost 1.72.0
build_pin_dep gflags 2.2.2. What can I do to continue installation?
