Undeploy isn't needed to my knowledge, seems more like a supersticious focus (or possibly a vestigial operation from before my time). In reality the deploy operation FTP's the compiled .out to the robot, overwriting the existing file, I assume undeploy removes the file, but you can redeploy over the file just as easily.

Have you reimaged your cRio with the new imaging tool for 2013? The updated image would be required for working with the updated WPIlib.
