[racket-dev] REPL broken for #lang racket language?

It looks to me like my drracket REPL is unusable. To wit:

1) unset PLTCOLLECTS.
2) move ~/Library/Racket
3) move ~/Library/Preferences/*racket*
4) start drracket
5) Choose "Use Language Declared in Source"
6) Run
7) In REPL, evaluate 13
... get this error message: 

compile: unbound identifier (and no #%app syntax transformer is bound) at: module in: (module program racket/base)

Could I be doing something dumb here? If I don't hear from anyone, I'll file this as a bug report.
