The docs likely need to be clarified that this applies if the two
recipes provide identical things. If one provides something and the
other does not, the behaviour is very different. Here, that message
means they are providing different things.

Cc: Scott in case he wants to clarify this in the docs and/or add more
information about this error message (see my other reply to this
thread).
