I can neither find mt-daapd.conf or config.xml, any pointers?
mt-daapd.conf is renamed firefly.conf and is at /yourusername/Library/ApplicationSupport/Firefly
I may be wrong but I think that blurb about the config.xml is a red-herring – that may be a leftover from a previous SVN. At any rate, I show that warning on both my instances of firefly (one for the G5, one for my NSLU2) but AFAIK it does not adversely affect control/operation of Firefly.
