You could replace @INC with a single code ref that rejects attempts to require certain packages, otherwise it searches @INC itself. Note that this answer demonstrates that I know that you can put a code ref into @INC but that I don't know if such code refs can prevent subsequent entries from being search or if you can temporarilly override @INC and re-require within the ref'd code.
