A simple example using Mac OS X

Using Leopard (Mac OS X 10.5)

Subversion is installed automatically on systems running Leopard.

From a terminal window the commands shown in the Linux example should work in exactly the same way. 

Using Tiger (Mac OS X 10.4) 

A subversion client will need to be installed and possibly your path updated to find the commands. The site for all Subversion downloads is http://subversion.tigris.org/project_packages.html. Currently http://downloads.open.collab.net/binaries.html provides Mac OS X binaries for download.

There is also a version available from Apple Developer as well as various free and open source GUIs.
