	When you get a message like "can't call XXXXXX on an undefined value"
it means the object you are trying to call the method on didn't initialize
properly. Look at the line the error occurred on, figure out what kind of
object it's supposed to be, then figure out why it isn't.
	Typically when you create an object using the 'new' method of a
module, the module is nice enough to provide some sort of error handling.
Typically for IO modules you can look at "$!" to find out what the error was.

	Btw, normally people post error messages in text along with the code
snippet causing the error. I have to say I got a pretty good chuckle from
the screenshot with the big red arrow.
