It appears more logical if you write
"duration32" = #(ly:make-duration (ly:intlog2 32))
\void \displayMusic \"duration32"
Not a particularly great kind of syntax but it seemed better than not
being able to express this from LilyPond.
You can, of course, also write $duration32 instead. It's pretty
equivalent to \"duration32" except that the latter is delimited (and so
does not need a space following it) while the former uses Scheme syntax.
