selfupdate fail

i encountered the following problem while trying to run selfupdate. i've tried to search this on the forums, but even though some people have asked this in the past, i did not see a solution that worked for me. i'm not using a firewall. $ sudo port -v selfupdate Synchronizing local ports tree from rsync:// rsync.macports.org/release/ports/ rsync: failed to connect to rsync.macports.org: Operation timed out (60) rsync error: error in socket IO (code 10) at /SourceCache/rsync/rsync-35.2/rsync/clientserver.c(105) [receiver=2.6.9] Error: Synchronization of the local ports tree failed doing rsync Error: /opt/local/bin/port: port selfupdate failed: Couldn't sync the ports tree: Synchronization of 1 source(s) failed
