Thank you for your thoughts. I've done some digging and I'm not sure
hdf5_light_reader.so has anything to do with this. In yt/pmods.py, if
I do

with mpi_import():
    import h5py

I still get basically the same error I pasted before. However, nothing
yt-specific should be touched, right? Right now I suspect that there's
some issue with how h5py is importing modules and how mpi_import()
handles stuff... I'll keep digging.
