State-Changed-From-To: open->closed
State-Changed-By: naddy
State-Changed-When: Sun Apr 27 12:38:03 PDT 2003
State-Changed-Why: 
musicbrainz has been repo-copied to libmusicbrainz and updated     
to 2.0.1.  They conflict with each other, and the old musicbrainz 
port will retire when zinf supports libmusicbrainz 2.0.1.
