What platform and version are you using? Places should be enabled by
default since 5.1.2 on most platforms.

Are you looking at the example

 (let ([pls (for/list ([i (in-range 2)])
               (dynamic-place "place-worker.rkt" 'place-main))])
    (for ([i (in-range 2)]
          [p pls])
       (place-channel-put p i)
       (printf "~a\n" (place-channel-get p)))
    (map place-wait pls))

and wondering how to replace the "place-worker.rkt" with something that
works in an executable? Use `define-runtime-module-path'.

Another possibility is to use the `place' form instead of
`dynamic-place'. The new Guide section (which I see is not linked as it
should be from the Reference section) provides an example using
`place':
