Not on any of the J systems I've tried! (Including Linux, Win32(Wine), or Windows Mobile / PPC)
I thought it was just a weird peculiarity of J, obviously d. "should" work on a user defined verb if it can. I tried with other verbs, like p. too, just in case o. was causing the problem. Nope, once you define a verb in terms of its primitives d. don't work no more.
