Re: compiling hdf5 with openmpi support?

[Thomas Klausner <wiz%gatalith.at@localhost>]

Hi Jay!

You stumbled over a bug that I also stumbled over - I've fixed that
when adding the option.

The option was only added in pkgsrc-current, so it will have no effect
on pkgsrc-2025Q4.  Please try pkgsrc-current, or wait for 2026Q2 (but
that's still > 2 months off).

Thanks,
 Thomas
