[racket] how to declare dependency on Racket 6.0?

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?
