Just to resurrect this one........I'm sure at some time in the past, the sump plug was overtightened somewhat, that displaced or bent a flange that the plug was surely intended to tighten up to - therefore a replacement sump will probably be the answer. The threads on the original sump are fine.
However, the plug seems to be well gummed in place so I'm leaving it well alone, and if I do see the car again for an oil drop I'll just pump the old lube out.
