Help with systemSeparatorMarkup in Latex

[Daniel Tonda]

I don't seem to get the "//" systemSeparator when using latex and lilypond. 

I've been searching and can't find any pointers. 

I put this code in a lilypond file, and when compiled by itself it shows fine in the final pdf, but if I use it in latex I don't get the separator.

\paper {
  between-system-space = 1.5\cm
  between-system-padding = #10
  ragged-bottom=##f
  ragged-last-bottom=##f
  systemSeparatorMarkup = \slashSeparator
}
