Well, I use this:

  (packages
     (append
       (map specification->package+output
          '("bind:utils" ... ))
     %base-packages))

But I am new to scheme/guile/guix, so maybe I do something wrong. Anyway,
thanks for confirming that it works on your side. It's probably an issue
with my configuration. :)
