There are several ways of doing that with asdf. The simplest is to
use :load-source-op instead of :load-op.
Example:

(asdf:oos 'asdf:load-source-op :hello)

[at least on asdf revision 1.98 it works]



Here's another (more complicated) example
(by Gary King):

(defclass load-only-file-mixin ()
    ())

(defclass load-only-cl-source-file (load-only-file-mixin cl-source-file)
    ())

(defmethod perform ((op compile-op) (component load-only-file-mixin))
    nil)

(defmethod perform ((op load-op) (component load-only-cl-source-file))
    (load (component-pathname component)))

(defsystem asdf-binary-locations
    :version "0.1"
    :author "Gary Warren King <gwking at metabang.com>"
    :maintainer "Gary Warren King <gwking at metabang.com>"
    :licence "MIT Style License"
    :description "Put compiled Lisp files in their places."

    :components ((:module
                  "dev"
                  :components ((:load-only-cl-source-file "main")

                               (:static-file "notes.text")))

                 (:module
                  "website"
                  :components ((:module "source"
                                        :components ((:static-file
"index.lml")))))))
