That should work, although it's better to declare a dependency on "base" instead of "racket":
(define deps '(("base" #:version "6.0") ... ) You should generally declare a dependency on "base", anyway. At least, that's the right way for v6.0 and later. If the goal is to get a nice error message from v5.3.x, then you have to * use the old format without `#:version`: (define deps '(("base" "6.0") ... ) * use `#lang setup/infotab` instead of `#lang info` for the "info.rkt" file, and * declare the dependency on "racket", after all, since "base" didn't exist as a package in v5.3.x: (define deps '(("racket" "6.0") ... ) For a while in v6.0.x, there were some problems with dependency checking in `raco setup` when a package declares a dependency on "racket". Otherwise, even though declaring a versioned dependency on "base" is better, declaring a dependency on "racket" should work. Can you say more about how it went wrong?
