Restarting doesn't help me, nor does doing raco setup.  In fact, I can
replicate the error on a clean installation of Racket 5.0.2.

I did a fresh installation of Racket 5.0.2, and I completely wiped out
my .racket to make sure some lingering PLaneT package wasn't
interfering, but I still see the error on executing test-when.rkt in
DrRacket.  I do not see the problem under the console with regular
racket.

What else can I do to help trace this error?
