I corrected it to your advice accordingly.

(defmethod output-files ((operation compile-op) (component foo-file))
  (multiple-value-bind (pathnames translatep)
    (values (mapcar #'(lambda (p)
                        (make-pathname* :directory (append
(pathname-directory p) (list (cond
((featurep :foo1.0) "1.0") ((featurep :foo1.1) "1.1") (t (error "No foo
feature found."))))) :defaults p)) pathnames)
