[racket] Error running whalesong: wrong number of fields for structure mod: expected 16 but got 15

Good evening,
I'm using Racket 5.3.6 under windows XP
When I obtain the whalesong package as follows:
#lang racket/base
(require (planet dyoo/whalesong:1:21/make-launcher))
then attempt to run whalesong at the command prompt as follows
C:\Documents and Settings\Galler>whalesong
I receive the follwing error

Application 
Data\Racket\planet\300\5.3.6\cache\dyoo\whalesong.plt\1\21\parser\parse-bytecode-5.3.rkt:372:20:

Any suggestions would be greatly appreciated.
Thanks much.
