I don't see anything that fits very well.ERRCODE_OBJECT_NOT_IN_PREREQUISITE_STATE is something we use in some other places where the meaning is "just wait awhile, dude". Or you could invent a new ERRCODE.
OK, did that. Here is a patch that is undocumented but I think is otherwise complete. It's been tested a bit and we haven't been able to break it. Comments welcome.
