If I understand correctly what you want to achieve (that "bug1.lisp" is
compiled and loaded before "bug2.lisp"), then this is usually
done by

  (defsystem bug
    :components
    ((:file "bug1")
     (:file "bug2" :depends-on ("bug1"))))

Or alternatively,

  (defsystem bug
    :serial t     ; sequential dependency graph along textual order
    :components
    ((:file "bug1")
     (:file "bug2")))

(s/:file/:cl-source-file/g if you want so but that distinction is
usually not needed.)
