The page says the "Convert CSV to SQL" action is in the standard Automator library, but I didn't find it and it doesn't seem to be on my system.
However, since this page you referenced is on the developers site, I'd suspect the actions it lists would be available if you installed the developer tools from you system disks that came with your computer (or the OS upgrade if you've upgraded since then). You'll likely also want to log in and download any updates to the developer tools from the ADC site.
Just guessing since I don't have the developers tools installed, though it seems the most plausible excuse for it saying it's there when it isn't. 🙂
However, I'm quite convinced it would be so, since one of the actions listed is "Build Xcode Project". Xcode is only available once you've installed the developer tools, so it makes since the Automator actions wouldn't be available unless you had it installed. Other actions in that list appear to be the same in that way. And I do remember seeing the "Build Xcode Project" action when I used to have the developer tools installed, so I'm quite confident this is the case for the other actions, too.
