No, this is not how the RRECOMMENDS mechanism works. There must be at least a 
possibility that the item in there exists (i.e., there must be a recipe that 
has it in its RPROVIDES, PACKAGES or an expression that would match it in 
PACKAGES_DYNAMIC). However, if a package corresponding to that item doesn't 
actually get produced, that is the situation that is ignored.
