  # This is a fairly nasty hack to avoid backporting 10k+ lines of
  # changes in patch format. It should be reverted to use the SF tarball
  # as pointed to on the upstream website on next release.
  # One of the resources, lwt, was updated in an incompatible way,
  # but the older versions of lwt no longer support the ocaml Homebrew
  # ships since May 5th 2016. Upstream pushed changes to fix this
  # but those haven't made it into a stable release yet.
  # There's also a build fix for Ocaml 4.03.0 not in latest release.
