After installing CouchDB via MacPorts, running Futon shows a message about an admin party:
“Welcome to Admin Party! Everyone is admin. Fix this”
After clicking on the “fix this” link and supplying a new admin user name and password, the dialog box hangs around for ever.
The solution is to fiddle with ownerships and rights:
sudo chown -R couchdb:couchdb /opt/local/etc/couchdb/
sudo chmod -R 0770 /opt/local/etc/couchdb/
Then retry.
