Speaking as a machinist I would bore the hinge just enough to clean up the worn area and make the hole round again. While doing this it is important to make sure the center-line of the hole is in the same location as it was originally so that the door position remains true. Now you can fabricate a thin wall bronze bushing to fit. Delrin bushings are nice but may not be useful if the wall thickness is too thin. Any competent machine shop should be able to fix you up. I would have him make you a couple of extra bushings while he is at it. If you notice any wear in the future it will be easy to push in one of your spares.
