It seems that nvim changed the version to 0.1.3-dev instead of 0.1.3-223 and current SConstruct can not detect the version correctly. I remove sys.exit(-1) to make the gnvim compile and it is running fine now. Seems something need to change in line
fmt_ver = lambda ver: ('%s.%s.%s' if len(ver) == 3 else '%s.%s.%s-%s') % ver

Don't know why this happens but you're right, it's a pain. Looking into it here: https://github.com/neovim/homebrew-neovim/issues/135

Tempted to just remove the version check and let --HEAD users fend for themselves, now that we've got a stable version.

I've added logic to bypass this check if you get -dev. You'll have to manually make sure your Neovim is up to date (latest master).
