2htdp/planetcute ambiguous binding error

[tonyg]

Program:

#lang racket
(require 2htdp/planetcute)
character-cat-girl

Expected outcome: Successful compilation; single image result (from the value of character-cat-girl)

Actual outcome:

character-cat-girl: identifier's binding is ambiguous
  context...:
   #(1972 module) #(1973 module t 0) #(4134 local) #(4135 intdef) #(4136 macro)
   #(4137 macro)
  matching binding...:
   #<module-path-index:((lib "character-cat-girl.rkt" "2htdp" "planetcute"))>
   #(1973 module t 0) #(4137 macro)
  matching binding...:
   #<module-path-index:(2htdp/planetcute)>
   #(1972 module) #(1973 module t 0)
  in: character-cat-girl
  context...:
   standard-module-name-resolver

It also produces an error in DrRacket's BSL and ASL (with the #lang line removed, of course).

Racket version:

~$ racket --version

However, it works to do this, and use character-cat-girl* uniformly in place of character-cat-girl:

(require (rename-in 2htdp/planetcute [character-cat-girl character-cat-girl*]))
