Huh. It seems to fail with a similar error message using pasterack.org: http://pasterack.org/pastes/72311
But it works for me on all the various Racket versions I happen to have installed on OS X (5.3.5, 6.0, 6.1.1, 6.1.16) as well as on 6.0.1 on Ubuntu. ____________________ Racket Users list: http://lists.racket-lang.org/users
