I have added new bit pattern constants (like user-permission-bits) to racket/collects/racket/file.rkt , but after make derived and make they don’t show up in the built interpreter. The interpreter seems to be the correct one according to which racket and it contains the new file-or-directory-stat function. The “old” bit patterns are available in the interpreter, so it doesn’t seem to be a require issue.

What else do I possibly need to do to get the new constants in the Racket interpreter?

Solved.
