I am running emacs-repository-version "846ff294206c922da4c48396e440e90179ffe070" * commit 846ff294206c922da4c48396e440e90179ffe070 (HEAD -> master, origin/master, origin/HEAD) | Author: Lars Ingebrigtsen | Date: Mon Nov 8 08:01:07 2021 +0100 So that could be the problem. I just tried https://github.com/jkitchin/org-ref.git but make fails as well (cask not found). I opened an issue on github. I will restart emacs and try it again.
