Yes!  Your problem isn't to do with hpricot vs nokogiri, but that the
links api has changed.  "links" returns a normal array now, so you
can't call "text" on it.

try this:

  unless logged_in_page.links_with(:text => /link text to find/).length > 0
    ...
  end

If you're only calling methods on mechanize, you shouldn't need to do that.
