First, tell subversion to use your proxy to connect to the server:If $prefix/var/macports/home/.subversion/servers doesn‘t exist, create it by copying the corresponding file from another user. (SVN automatically creates this file if it doesn‘t exist.)Edit the file and set a proxy for hosts at *.macports.org. Different proxy configurations require different sets of options here, but the file is pretty well commented, so it should be easy to figure out what you need. At a minimum you‘ll need settings for http-proxy-host and http-proxy-port.Finally, if you want to use SVN over HTTPS to access the repository, you‘ll need to tell SVN to trust the MacPorts signature. (SVN doesn‘t trust the authority that issued it, and port sync below invokes svn up with the --non-interactive flag, so you won‘t have the opportunity to accept the certificate then.)mkdir -p $prefix/var/macports/home/.subversion/auth/svn.ssl.serverAs a normal user, run svn ls https://svn.macports.org/repository/macports/trunk/dports/. When prompted, accept the certificate permanently.SVN will store the certificate in a file in the directory $HOME/.subversion/auth/svn.ssl.server. In that directory, find the file that contains the string "https://svn.macports.org" and copy it into $prefix/var/macports/home/.subversion/auth/svn.ssl.server.
