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))
