It means exactly what it says, those functions aren't available in your script. I don't know how you want us to help with that, we don't know what the functions are, what they are supposed to contain. All I know is that they aren't native functions so there's no documented information on the Wiki about them!
I don't know how else we can help you with that. You need to make those functions.
