 Greetings. When I try to self update ports, I receive and HTTP error
 message:

 [09:45 user at host ~] > sudo port -v selfupdate
 --->  Updating MacPorts base sources using rsync
 rsync: server sent "HTTP/1.0 500 handshakefailed" rather than greeting
 rsync error: error starting client-server protocol (code 5) at

 Command failed: /usr/bin/rsync -rtzv --delete-after

 Error: /opt/local/bin/port: port selfupdate failed: Error synchronizing

 The rsync command works outside of the selfupdate:

 [09:45 user at host-mitll ~] > sudo  /usr/bin/rsync -rtzv --delete-after
 rsync://rsync.macports.org/release/tarballs/base.tar
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs

 receiving file list ... done

 I am behind a proxy:

 [09:52 user at host-mitll ~] > sudo env | grep http
 http_proxy=http://xxx.xxx.xxx.xxx:8080

 https_proxy=http://xxx.xxx.xxx.xxx:8080




 Any ideas? Apologies for the formatting; I couldn't get the wikiFormatting
 to do its thing. Basically, the rsync command doesn't work within
 selfupdate, but does if I just do it manually. This complicates my
 debugging.
