Comment (by dfleck):

 Actually I *have* mythbackend (and mythweb) running on the M1. I installed
 a v28 app package I found somewhere. But I'd like to get it running
 "properly" as a service thru MacPorts (plus the webbackend server isn't
 working right with the app).

 I'll try to modify the Portfile - but so far I've been flummoxed with
 updating the checksums.
