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 mapd-deps-osx.sh 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?
