@ocefpaf see SciTools/iris#4418. However I don't know why this is still failing since this PR is dated entirely after that Iris PR.

I guess there isn't a release with that PR, so we are still getting the version without that change. I backported it in #75 and it should cover the python migration as well b/c we no longer need it.
