metacall being abolished.

In one file I have this:
model_post(Spec) :-
model:maplist(ignore, Spec).

Subsequently when I recompile model.pl, I get this error:
        Loading module model abolished: [model:__aux_maplist/2_ignore+0/1]

and
Warning: The predicates below are not defined. If these are defined

Warning: at runtime using assert/1, use :- dynamic Name/Arity.
Warning: 
Warning: model:'__aux_maplist/2_ignore+0'/1, which is referenced by...


The aux predicate should have been created in the 
other module.  The only remedy I can think of is to manually force the original 
file to recompile every time.  This is a major nuissance.
