Hello Guix,
since "netcdf-cxx4" is a C++ interface to the C library "netcdf", I think the
latter should be a propagated input.
Similarly, since "hdf5-parallel-openmpi" includes mpi.h in the hdf5.h
header file, then "openmpi" should be a propagated input of
"hdf5-parallel-openmpi".
Let me know what you think.
Cheers,
Luca

yes, I agree.

I think mpi is really special in this respect, I am not aware of other
software in the same category. And "needed at runtime" is not enough.
As written before, there is usually no problem with libraries for which
we set the rpath to an absolute path in the store. Well, then usually
the dependency sneaks in through include files.

Closing this issue.

Andreas
