Well, inside of #{ ... #} there is music by default. If you want to
have an output block, you need to place it there. For me,
\version "2.16.2"
\paper {
$(if (ly:get-option 'binder-margins) #{
\paper {
left-margin = 20
line-width = 5
}
#})
}
\score { \relative { c4 d e f g a b c } }
appears to do the trick.
