If it works by just setting the environment variable, then perhaps the package should be bundled so that the binary is in libexec/ and a wrapper script takes its place in bin/.

HDF5 takes a very conservative approach and checks compiled with /
running with version numbers at launch. It's software designed for
maintaining huge and potentially expensive / impossible to replace
scientific data, so they go with error out and print a message rather
than any tiny chance of cross-version issues. These errors can be
suppressed and it will run, as mentioned in the original message to
the list. This isn't the recommended mode of operation.

I'm about to revbump the portfile, which will fix these issues, as the
binary package will get recompiled against the new hdf5-18. I try to
keep on top if it (the hdf5-18 portfile change happened 48 hours ago
or so) but I am still recovering from jet lag...
