I read somewhere that reggae builds itself. I'd suggest a way to build reggae with only OS-provided common tools, since you'd have to include it in the toolchain in order to build dmd/phobos otherwise.
It can build itself, yes. Since I've only developed and tested it on Linux, the `bootstrap.sh` script in the repo builds it by calling dmd on all the sources. After that it can (and does) build itself. There'd have to be a .bat for Windows but any other POSIX system should be able to call `bootstrap.sh`.
