I'm still cutting my teeth on Scheme, and this looks like a simple
error, but the following from my manifest results in the error below.
The function accepts a package to inherit from and a list of files to
rename by appending the package name. This works if I change to pass
in a single string and create the list within the for-each argument.

(define (rename-files parent-package files)
  (package/inherit parent-package
    (arguments
     (substitute-keyword-arguments (package-arguments parent-package)
       ((#:phases phases #~%standard-phases)
         #~(modify-phases #$phases
             (add-after 'install 'rename-files
               (lambda* (#:key outputs #:allow-other-keys)
                 (let ((out #$output) (name #$(package-name parent-package)))
                   (for-each
                     (lambda (file)
                       (rename-file (string-append out "/" file)
                                    (string-append out "/" file "-" name)))
                     #$files))))))))))

(define moreutils-decollide
  (rename-files moreutils (list "bin/parallel")))
