This means you still have files hanging around that were compiled with
an older version of SBCL (and which are incompatible with the version
you're currently using).  The immediate cure is to delete all relevant
.fasl files and try again.

A prophylactical way to deal with errors like this one is to put this
method definition into your init file - it'll also work with AllegroCL
and LispWorks:

  (defmethod asdf:perform :around ((o asdf:load-op) (c asdf:cl-source-file))
    (handler-case (call-next-method o c)
      (#+:allegro excl::file-incompatible-fasl-error
       #+:lispworks conditions:fasl-error
       #+:sbcl sb-ext:invalid-fasl 
       #-(or :allegro :lispworks :sbcl) error ()
       (asdf:perform (make-instance 'asdf:compile-op) c)
       (call-next-method))))
