 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
