If you want to include lilypond syntax inside scheme syntax you have to
put #{ #} around it. Here is your second example, with that included
(which made the error go away for me):

\layout {
  \context {
    \Voice
    \override Accidental.before-line-breaking =
    #(lambda (grob)
       (if (eqv? (ly:grob-property grob 'alteration) SHARP)
           (begin
            (ly:grob-set-property!
             grob 'horizontal-skylines ly:grob::horizontal-skylines-from-stencil)
            (ly:grob-set-property!
             grob 'text #{ \markup \vcenter \huge \bold "$" #})
            (ly:grob-set-property!
             grob 'stencil ly:text-interface::print))))
  }
}

Hope that works for you
