The official release of GRIP doesn't support Raspberry Pi yet. The linux version in the downloads is for x64 processors, and the deployable roboRIO binaries are for the arm-softfp ABI (the raspberry pi is arm-hardfp)
Someone did manage to get a version built for the Pi, though. I haven't personally tested it, but it looks promising.
