I'd say: the moment you change the original source code, you "derive work from" it in terms of the GPL. Therefor, you should concider this (derived) work as yours and put your name in the notice. It would definitely be nice if you included information on what original work your file is based, but the only _obligation_ you have ist to publish your file.rb under the terms of the GPL as well.
