The ownership of the files in /opt/local/var/macports/sources/rsync.macports.org should not matter. By default they will be owned by the uid and gid that are used on our main rsync server, which happen to be uid 500 and gid 505, but those aren't necessarily meaningful uid or gid values on your system.

Check the ownership and permissions of each directory leading up to that one, though:

ls -ld /opt /opt/local /opt/local/var /opt/local/var/macports /opt/local/var/macports/sources

Are read and execute permission ("r-x") for every user present for each of those directories?
