lyluatex: cannot \include lilypond file

[Federico Bruni]

Hi folks

I'm trying to include a simple .ly file in the same directory of my 
.tex file.
Why it's not working?


$ cat nostringnumber.ly
\layout {
 \context {
   % Do not display string numbers on Staff (I use TabStaff also)
   \Staff
   \omit StringNumber
 }
}


$ cat rel.tex
\documentclass{book}
\usepackage[includepaths=./]{lyluatex}

\begin{document}

Trying to include a LilyPond file:

\begin{lilypond}[nofragment]
\include "nostringnumber.ly"
music = \relative {
 \time 2/4
 c4\3 e\2 |
 c2 \bar "|." |
}
\score {
 \new PianoStaff <<
   \new Staff { \clef "treble_8" \music }
   \new TabStaff { \clef "moderntab" \new TabVoice \music }
 >>
}
\end{lilypond}

\end{document}


By the way, I guess that the ./ includepaths is not necessary, right?
Anyway, whatever I do (use it or not), here's the error I get:
