Add a TOOL_DEPENDS like so:

TOOL_DEPENDS+=	${RUBY_PKGPREFIX}-ronn-[0-9]*:../../devel/ruby-ronn

.include "../../lang/ruby/rubyversion.mk"

The executable installed by ruby-ronn is version-suffixed - there
are a few approaches you can take here.

The best is probably patching the build system, use a variable
substitution to replace the executable name with ronn${RUBY_SUFFIX}.
You could also install a symlink to the tools dir.

If the build system does not automatically create the manual page,
it might be easier to define a target in pre-install or similar.
