When I run the sample first Rucku program as instructed in [2&nbsp;Getting Your Ruckus On](https://docs.racket-lang.org/ruckus/Getting_Your_Ruckus_On.html)

```scheme
#lang ruckus
 
(sphere 200)

```

it fails. It writes out a lot of C code on my terminal, then complains

```scheme
generate-compile-and-link: error compiling: 0:1(1): error: syntax error, unexpected end of file

It turns out to have been a version skew problem. Ruckus works fine with an up-to-date Racket.
