FWIW, I would just use Homebrew to install `dmd` and save myself 
a lot of trouble.

Although, you probably want to go with LDC instead of DMD on Mac 
because debug infos are utterly broken (among other things).
See [this report](https://issues.dlang.org/show_bug.cgi?id=20460) 
for the DMD bug, and [this 
report](https://issues.dlang.org/show_bug.cgi?id=20510) for why 
things won't work out of the box on any compiler.
