Hi all, I'm trying to get the frameEngraver3.ly code from this aleatoric notation thread going on Lilypond 2.16.0-1, and I get the following errors:

fatal error: failed files: "frameEngraver.ly"
I can't code in Scheme, and I've yet to find any tutorial in the Lilypond
docs that would get me to this level of Scheme integration with Lilypond.
But it seems to be the case that it throws an error once for a scheme
function and again because of expected typing. Since a subsequent (relative
to the message to which frameEngraver3.ly was attached) message in the
thread recommended revision to frameEngraver3.ly, specifically the addition
of "\frameStart" command marks after the frame's first pitch, I've attached
my copy of the file to make it clear which code exactly has generated these
errors.
This might be a good scheme lesson for me, right here, come to think of it.
I've got LISP, so maybe I'm not as far as I think.
best,
Jeff
