lyluatex can't execute Lilypond

[N. Andrew Walsh]

Hi List,

Urs and I are having trouble figuring out why my version of lyluatex isn't working. I have the following MWE:

\documentclass{scrartcl}

\usepackage[program=/path/to/lily/wrapper/lilypond]{lyluatex}

\begin{document}

\begin{lilypond}

c'

\end{lilypond}

\end{document}

but the command 'lualatex --shell-escape test.tex' ends with this error:

 (/usr/share/texmf-dist/tex/latex/oberdiek/epstopdf-base.sty
