No, it's not using the compiled version. The `(require
"constants.scm")' in "main.scm" is resolved when the module is
executed, no matter how the module is compiled. And the only candidate
found for "constants.scm" is the source.

If you use the --auto-dir flag with mzc, then it will put "_loader.so" in
the right place so that `(require "main.scm")' will use "_loader.so", and
`(require "constants.scm")' will also use "_loader.so", and so on.
