From my understanding of modder etiquette/rules, you're supposed to ask permission if you wish to use the original author's work (as is?). However, since much of what is modded is often a reworking of a game's original files, is it realistic to expect modders to go to the original programmer of a specific file and ask permission to modify said file? If you don't go that far with the game's original author's work, why should you with another modder? I think that you should at least tip your hat in your read me file, but that if you're only using the other modder's work as a starting point....well isn't that what he was doing from the box, so to speak? As long as they are only taking credit for their tweaking, versus passing it off as completely original, I'm not sure it should be a real big deal. lies have a way of catching up with people.
