alignment-offsets has been replaced with alignment-distances and the
semantics have changed too: alignment-distances gives the distances
between staves (but not Lyrics or other loosely spaced lines) so its
length should be one less than the number of staves. Also, you can set a
forced distance of 23 for any of the xxx-spacing variables with

xxx-spacing = #'((space . 23)  (minimum-distance . 23) (stretchability .
0))

Let me know if there is functionality that you can't achieve with these
settings.

Cheers,
Joe
