Package: bitshuffle Followup-For: Bug #955456 Incidentally, Thorsten, another way of handling h5py and bitshuffle's build against hfd5-mpi is to explicitly access h5py-mpi.
That is, patch out bitshuffle to replace import h5py with import h5py._debian_h5py_mpi as h5py (in bitshuffle/h5.pyx and in tests). In that case h5py-mpi gets loaded directly by bitshuffle, so will be active even in a serial process.
