[plt-scheme] scribbling newbie

setup-plt: Docs failure: algol60.scrbl:4:1: compile: unbound variable  
in module in: title

I'm using a MacIntel with the Full nightly build.  Should it work with:

#lang scribble/doc
@(require scribble/algol60)

@title{algol library}

Welcome to my documentation: @scheme[(list 'testing 1 2 3)].
