Error The proof for your build plan contains domain assumptions. Please verify:


>>> Domain assumptions

- Unsatisfied constraints for install dependency: 
  sci-libs/hdf5:= [ hl(+) mpi= szip= zlib ]

  required by: portage://sci-libs/netcdf-4.10.1-r1

- Unsatisfied constraints for run dependency: 
  sci-libs/hdf5:= [ hl(+) mpi= szip= zlib ]
