I usually use this macro in a wrapper that require/provides the libs and provides compatibility wrappers when needed

;; compile time version switch
(define-syntax (version>=? stx)
  (syntax-case stx ()
    [(_ min-version body body-else)
     (if (string>=? (version) (syntax-e #'min-version))

Actually this issue is still perplexing me. In 5.2.1 I have my own json lib
which provides jsexpr->string. In 6.1 it's part of the distribution's
collects directory.

Is there a command line for racket that'll cause it to find mine under
5.2.1 and the standard lib in 6.1 (skipping mine)?

Ugh. Never mind... the old json lib is mine. Carry on :)

I'm maintaining the same racket code between Racket version 5.2.1 and
6.1. One thing that changed between those version was the json to string
(and vice versa) lib functions.

Is there a straightforward way to define those functions so they'll work
with both lib versions?
