MacPorts behind Firewall

1. Use http instead of rsync. Open the file /opt/local/etc/macports/sources.conf and replace the line

   rsync://rsync.macports.org/release/tarballs/ports.tar [default]
   

   with

   http://www.macports.org/files/ports.tar.gz [default]
   

2. Configure proxy.

   export http_proxy=http://username:password@proxyURL:portNumber
   export HTTP_PROXY=http://username:password@proxyURL:portNumberexport 
   export ftp_proxy=ftp://username:password@proxyURL:portNumber
   export FTP_PROXY=ftp://username:password@proxyURL:portNumber
   export rsync_proxy=username:password@proxyURL:portNumber
   export RSYNC_PROXY=username:password@proxyURL:portNumber
   

3. Use sudo port -d sync instead of sudo port selfupdate to print debugging information while updating.
