For anyone trying to install from Homebrew, the new formula hasn't been merged, you can brew edit it, if you need it now... Simply replace the existing formula, with the new one: https://github.com/josevalim/homebrew/blob/patch-30/Library/Formula/elixir.rb https://github.com/josevalim/homebrew/blob/patch-30/Library/... > brew edit elixir Then just paste the new file in. You'll have to reset this eventually... which you can do for all your formulas using: cd `brew --cellar` git reset --hard HEAD Installs like a charm on El Capitan.
