After many hours of searching and thinking I found the following code works:

#+BEGIN_SRC scheme
   (arguments
    '(#:phases
      (modify-phases
       %standard-phases
       (delete 'check)
       (add-after
        'wrap
        'include-curl
        (lambda* (#:key inputs outputs #:allow-other-keys)
          (wrap-program
           (search-input-file outputs "bin/nb")
           `("LD_LIBRARY_PATH"
             suffix
             ,(list
               (dirname
                (search-input-file inputs "lib/libcurl.so"))))))))
#+END_SRC

When I will have rested from this code adventure, I will make effort to 
publish the entire package set I created to make this program work.

Sincerely,
