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
