The `-I' flag just sets a module to `require' by default, so it's the
same issue as in Sam's question.
Probably you want to write "Z/main.rkt" itself in a language whose
runtime configuration is the same as for modules implemented with
`#lang Z'. See "racket/main.rkt" and "racket/base.rkt", for example,
which are implemented in the `racket/private' language.
