Hi, During a test rebuild of HDF5's reverse dependencies against HDF5 2.1.0 currently in experimental, h5py FTBFS because its build toolchain doesn't support this new major release. The attached patch is a workaround for this issue and supports both HDF5 1.14.6 in unstable and HDF5 2.1.0 in experimental.
