How can I tell TeX Live Utility where my TeX distribution is?

Rather than installing a new version of TeXLive, a better solution might be to install the latest version of MacTex, which contains a stable version of TeXLive and Tex Live Utility. I'm downloading that now...If I don't post that this was successful in a day or so, shoot me a reminder!
