There is a Chicken 4 egg yaml that wraps libyaml. The source from its gihub repo doesn't compile, because there is a missing <field spec> in a define-record-type form. I submitted a issue about this at the github repo with a patch that changes one line and adds one line, which seems to fix the problem. There is a fork of that github repo that also fixes the problem, but it hasn't been fixed in the original repo.
I'd like to see this as a Chicken 5 egg. What is the proper way, considering the social and technical aspects of things, to getting this submitted as a Chicken 5 egg?
