What material are you referring to? SICP & co.? Unfortunately, =E2=80=9Cthe=E2=80=9D Scheme language is more of a concept; = SICP targets R5RS I think, which happens to work with most =E2=80=9CScheme implementatio= ns=E2=80=9D, but not necessarily by default (what if you use =E2=80=9C#lang racket=E2=80= =9D for instance?).
