Comment (by Dave-Allured):

 @sivanadarajah, port {{{hdf5-18}}} is obsolete.  It was replaced by port
 {{{hdf5}}} more than two years ago.  See ticket #55568.  All modern ports
 that used {{{hdf5-18}}} have switched over to port {{{hdf5}}}.

 Can you use the current {{{hdf5}}} port for your application?  It is
 currently updated to upstream version number HDF5 1.10.6.  This works
 well; I use it all the time.

 HDF5 offers a version compatibility system that allows you to compile
 older code with a newer HDF5 library version, with few or no code changes.
 In short, add the flag {{{-DH5_USE_18_API}}} to the compiler command line.
 If you are compiling older code that worked with 1.8.x, this may be very
 helpful.
