Subversion on a Mac 10.4 (Tiger), behind a firewall

The Subversion project recommends:

• THIS ONE WORKS: MacPorts - has a .dmg installer for 10.4 
• need to set environment variable http_proxy if behind a firewall
• then the sudo port -v selfupdate command
• then do sudo port install subversion 
• Warning: The installed version of Xcode (2.3) is known to cause problems. Version 2.5 or later is recommended on Mac OS X 10.4. Download Xcode tools.
• Fink - wouldn't install for me, saying "Cannot perform symlink test on this volume because of a permissions problem". Running "Repair Disk Permissions" utility as recommended doesn't help at all.
• Apple's Developer Tools - I don't think it's on the CD. Couldn't find a list of apps anywhere. When I tried, it installed a lot of stuff but I couldn't see svn anywhere.
• OpenCollabNet - ?
