ruby upgrade

[Aaron Sloan]

Good morning,
I'm having some troubles getting started on how to
search the ports I have installed who have ruby as a dependency so
I can upgrade them.  What syntax do I need for searching of which file?

I have looked at the syntax from the perl portupgrade and I'm scared...  : )

portupgrade -f `(pkg_info -R perl-5\* |tail +4; \
        find /usr/local/lib/perl5/site_perl/5.[68].[1245] -type f -print0 \
        | xargs -0 pkg_which -fv | sed -e '/: ?/d' -e 's/.*: //')|sort -u`

Just a pinch above my head.
Help would be appreciated.
I have RTFM but I still need a little direction.

Thanks!
Aaron
