Oh dear, yes. Mine pulls it in via quicklisp (did I mention that
quicklisp is a livesaver ;-)

That's ugly. In general, *-user packages are meant for interactive 
REPL experimentation, not for written code.
It used to be the case that one would write:

(defpackage :clm-asdf (:use :cl :asdf))
(in-package :clm-asdf)

 ...

But that seemed so wrong for a file with purely delatative syntax (hint,
hint, looking atr you CM) that the gods of ASDF decided that none of
that trickery is needed. 
Just for the fun of it create foo.asd:

 (defsystem :foo
  :components ())

 (format *debug-io* "This is read in package ~A~%" *package*)

Then, do a (asdf:load-system :foo)

Nota bene: don't (load "foo.asd") - that would produce the error you
encountered.

I think this needs a bit of rework (pimp up my asd ...)

 ... or install quicklisp and put/link your extra code/projects into
 ~/quicklisp/local-projects.
