Which version of sci-libs/hdf5 you have installed?
I don't know if I upgraded between the bug reports creation and currently. I currently have version 1.8.18 installed.
This is caused by sci-libs/hdf5 built with mpi use flag. Silo uses old function name, which is deprecated and removed since hdf5-1.8.13. https://support.hdfgroup.org/HDF5/doc/RM/RM_H5P.html#Property-SetFaplMpiPosix I've attached a patch, please verify. It builds fine for me, but I'm not sure about further working.
I unmasked mpi on hdf5 and gave this a try, builds fine as far as I can tell. Likely got fixed by something in the last few years, but haven't looked deeper.
