science/hdf5 should be upgraded to 1.12, but some ports are not compatible with this version, and it has been suggested to repocopy the actual port to science/hdf5-110.
PR 251894 propose a patch to do that, and an exp-run has been launched to detect the incompatibilities.

(this looks like a missing -lz?)
Could you please propose a patch, either to fix it with 1.12 or to switch to hdf5-110?
