Still failing.  In ’compute-derivation’, this 

              (s
               (list (package-source-derivation store s)))))

returns a list of string instead of a derivation, so then

                          (for-each show-derivation-outputs drv)

fails because it expects a derivation or a derivation-input (see in
(guix ui)).

Well, I am not sure where the error should be handled.  In (guix ui) and
in (guix scripts build)?  WDYT?
