I had the same exact problem. The build failed, because it cannot find a boost header file. Try brew install boost.

I am curious, is it not looking for boost in its default root directory? I have boost header-only here in opt/local/include/boost according to the readme and slinked inusr/local/opt/1.68.0_1/include/boost but still return this failure.
(Edited for clarity, according to info from both the readme and closed issues)
