Hello,
I have managed to get another case of a binding not being available
according to the Guile REPL, this time I have the code and way to
reproduce the issue.
;; ===== HELPERS MODULE (networking-lib/helpers.scm) =====
(use-modules (rnrs bytevectors))
(define-module (networking-lib helpers)
? #:export (display-byte-vector))

With above code, bytevector import is NOT in the context of your
module.? Try
(define-module (networking-lib helpers)
? #:export (display-byte-vector))
(use-modules (rnrs bytevectors))
OR
(define-module (networking-lib helpers)
? #:export (display-byte-vector)
? #:use-module (rnrs bytevectors))

Thank you Matt, that worked.
Somehow I assumed, that it would "magically" make the used modules also
available in the code, which uses the helpers module.
Now I can have less/no code duplication : )

I have now changed the code and I have it here:
