rolled chords in mulivoice classical guitar score

[Tom Cloyd]

Greetings!

After digging around considerably in the excellent Lilypond 
documentation (am running 2.11.60 on Kubuntu Linux 8.04.1), and running 
a number of experiments, I'm defeated on this problem.

A simple test case: I have two voices in a single staff. Periodically, I 
want to indicate that the notea co-occuring at a given point are to be 
played as a "rolled" arpeggio. There is NO chord notated - just two 
voices with single notes. Please don't suggest I merge the voices. 
That's not the solution I'm looking for.

P. 90 of Lilypond Notation reference illustrates a rolled arpeggio 
across different notes in the same staff, but it involves notes in chord 
clusters. Besides, my Lilypond doesn't at all like this stuff (from the 
reference):

\new Staff \with {
 \consists "Span_arpeggio_engraver"
}
\relative c' {...

I get this error - "warning: cannot find file: `consists' "

So, even if I HAD chord clusters, I'd still have a problem.

This rolled arpeggio business is very common in classical guitar music. 
I'm a little surprised there isn't some simple way to indicate it, 
but...maybe I'm missing something.

Any help would be much appreciated!

Tom
