There is an obvious way to remedy that.
fixing the version alone doesn't help. One needs to tell the package where to look for cython headers, and the old way is broken. And the new way is reverted in https://github.com/sagemath/sage/pull/40877 (over my and others objections) so now https://github.com/sagemath/sage/issues/40726 is open again. > >- Marc > -- You received this message because you are subscribed to the Google Groups "sage-release" group.
