I'm finally getting used to using "man pkg-query" to access the man pages
even though the command is "pkg query ...".  An alternative method is
the "pkg help query".

I think what you're looking for is "pkg query %ro xxx".  Look under
Multiline Patterns in man pkg-query.  Note that it only lists run
dependencies since build dependencies are irrelevant with packages.
