It is part of the Mac OSX Developer tools which shuold have been included on the CD which came with your Mac. I believe you can also download it from the Apple Developers Site after registration.

Once it is installed you'll find it in /usr/bin/opendiff

opendiff is a command line tool. So, you should be able to open a terminal, then type opendiff -h. If it's installed, you should see a help file. If not, you'll get a 'opendiff: command not found' error message. I think opendiff is part of Mac OS X - I don't know that you can get it outside that.

If you're not wedded to some specific feature of opendiff, maybe GNU 'diff' will serve your needs? –  dublev Jun 18 '10 at 19:56
