meep fails with failure to load libhdf5_openmpi.so.10

[Ian Sage]

After upgrade from 16.04 to 18.04, and re-installing meep 1.3.4 from the repository packages, I try to run it with:
mpirun -np 6 python3 my_model.py
but the run fails:
import meep as mp
  File "/usr/local/lib/python3.5/site-packages/meep/__init__.py", line 28, in <module>
    _meep = swig_import_helper()
  File "/usr/local/lib/python3.5/site-packages/meep/__init__.py", line 24, in swig_import_helper
    _mod = imp.load_module('_meep', fp, pathname, description)
  File "/usr/lib/python3.6/imp.py", line 243, in load_module
    return load_dynamic(name, filename, file)
  File "/usr/lib/python3.6/imp.py", line 343, in load_dynamic
    return _load(spec)
ImportError: libhdf5_openmpi.so.10: cannot open shared object file: No such file or directory

(Repeated for each thread)
Examining my system, it seems only libhdf5_openmpi.so.100 is installed in 18.04?
