Where's Racket?

[Mark Carter]

I'm a little puzzled here. The Racket website seems to point to a
download of DrScheme 4.2.5. If I type the following example program:
#lang racket ; An echo server
(define listener (tcp-listen 12345))
(let echo-server ()
(define-values (in out) (tcp-accept listener))
(thread (lambda () (copy-port in out)
(close-output-port out)))
(echo-server))

in DrScheme, I obtain the response
Module Language: invalid module text
standard-module-name-resolver: collection not found: #<path:racket
\lang> in any of: (#<path:C:\Users\mcarter\AppData\Roaming\PLT Scheme
\4.2.5\collects> #<path:C:\Program Files\PLT\collects>)
Interactions disabled.

What gives? I'm using "Determine language from source".

It took a while to get all the little bits into place -- should be
working fine now.

Ah, OK, seems to be fine now. I'm a Scheme newbie myself, and was
interested in assessing it for the creation of a dynamic website.
