The message, though, has absolutely nothing to do with the IPAddress line.

So, somewhere, you have put a library in the Arduino library path that you should not have put there, and it is causing your problems. I suggest that you uninstall 1.0, and reinstall it.
What's with the -2 in Arduino-2.app? What version of the IDE are you really using?
That example is not the brightest example that Arduino team has foisted off onto unsuspecting users.
