[iglified@…]

I entered: $sudo port -v selfupdate in my terminal, and I got the error: /opt/local/bin/port: port selfupdate failed: can't create directory "/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/tmp": permission denied

I just want to install koffice, and I don't know anything about computer programing, could you please explain what I should do next? Please tell me in as simple terms as possible
