Ron,
It works now. Thanks for your help!
The long story is I went through and removed /usr/local/var/cache/mt-daapd/songs.db, and was monkeying about on the way to setting the -d9 flag. Well, I just happened to check df and noticed that the root partition was full. I had misplaced a copy command and had filled the /var/log directory with junk. So I cleaned it out and now all works! Chalk this one up to a case of PEBKAC.
I’m now enjoying my Roku SB served by mt-daapd! 🙂 Thanks again!
