Compiling from source (for Homebrew formula)

I have managed to make a working Homebrew formula which builds opendylan from sourche using dylan binary for bootstrapping, but i had to use 2 workarounds.

1. I had to set `ENV.deparallelize`.  Does it mean that opendylan cannot be built in parallel?

2. I had to use `--env=std`.  You can read something about Homebrew environments here:
https://github.com/Homebrew/homebrew/wiki/Formula-Cookbook#wiki-superenv-notes
This might mean that the building scrip relies on some unexpected environment variables, or that Homebrew's `superenv` breaks something when it tries to change flags in the commands passed to clang/gcc.  Any ideas?
