CL Wordnet Interface

Has anyone had any luck interfacing with the Wordnet database from 
Macintosh Common Lisp? I have tried using the code written in 1995 by 
Mark Nahabedian at MIT, but it does not work, e.g.

? (get-synonyms "car" :noun)
>  Error in process Listener: Not an integer string: " This software 
>and database is being provided to you, the LICENSEE, by  ".
>  While executing: PARSE-INTEGER
>  Type Command-. to abort.
See the RestartsŠ menu item for further choices.

Is there some code out there that people know will work? I am running 
Mac CL 4.2

    Thanks,
