This is happening with a clean initial installation. Two colleagues of mine have just encountered this problem and I have been able to replicate it as shown below. I’ve never opened an issue on github but will try to do do for HDF5. This also affects other packages such as JLD and JLD2 with HDF5 as a dependency.
