The crowbar 0.2 failure is interesting:

But unrelated

[hannesm]

what is missing here is a section:

extra-files: [
  ["config.patch" "md5=<>"]
]

at least with the upcoming change in opam ocaml/opam#5564 this extra-files section is necessary...

I like this change, thanks for pointing it out. I'll send a PR immediately.
