Knute,
In the original the first beat of the second measure is three against
2. The 5 against 3 does not start until the second beat.
Unfortunately, that can't be true, as with this interpretation, the
measure is over-full. Rather, the groups of quintuplets/triplets
continue, with a beaming not in sync with the measure's beat structure.
This also implies that the original engraving isn't mathematically
correct (as the beginnings of the bems groups look as if they're
aligned). Situations like that are hard to approximate with LilyPond, as
Lily has a strict binary notion of two notes being simultaneous or not.
One can try cheating a bit by engraving the measure according to its
visual apperance (3-vs-2 in the first beat, exact 4-vs-1 in the last
quaver of the measure), but then it will be necessary to compress
whatever will be in the measure to the duration of one whole note, and
it's not certain what LilyPond's spacing algorithm will make of it.
Sorry for describing the situation verbally; I'll try to cook up an
example as soon as I have time (later today).
