It seems the problem is McClim (!)

If you reproduce the problem and do:
0] (loop for (a name c d) in (nth 9 (SB-DEBUG:ARG 1)) do (format t
"~&~A~%" name))
package <- NAME package
feature-case
macros
tv
draw
present
extensions
wholine
export
package <- NAME package AGAIN!
copy
dump
duplicate
random
menu-tools
basic-classes
draw
mouse
color
basic-graph
graph-mixins
axis
moving-object
symbol
graph-data
legend
graph-classes
present
annotations
annotated-graph
contour
equation
popup-accept
popup-accept-methods
duplicate-methods
frame
export
demo-frame

So the problem is with McCLIM, or better with the defsystem macro in
McCLIM that defines system with duplicate names:
0] (in-package :mcclim.system)

#<PACKAGE "MCCLIM.SYSTEM">
0] (cl:macroexpand '(clim-defsystem (:scigraph :depends-on (:clim
:clim-looks))
  ;; The DWIM part of SCIGRAPH
  "Apps/Scigraph/dwim/package"
  "Apps/Scigraph/scigraph/package" ))

(PROGN
 (DEFSYSTEM :SCIGRAPH
            :DEPENDS-ON
            (:CLIM :CLIM-LOOKS)
            :SERIAL
            T
            :COMPONENTS
            ((:FILE "package"
                    :PATHNAME

#P"/home/pvaneynd/fakeroot/McCLIM/Apps/Scigraph/dwim/package.lisp")
             (:FILE "package"
                    :PATHNAME

#P"/home/pvaneynd/fakeroot/McCLIM/Apps/Scigraph/scigraph/package.lisp"))))
T

As asdf refers internally to subsystems only by name this is "a bad
thing" (TM).
