[tex-live] "pgfsys-luatex.def" not found

[Daniel Flipo]

Hi all,

With TL2016 pretest, the following test file requires a
"pgfsys-luatex.def" driver while compiled with lualatex. It required
"pgfsys-pdftex.def" with final TL2015.

I cannot install texlive-full due to a very slow internet connection and
I have not found out which package installs "pgfsys-luatex.def".
Can anybody help?

% To be compiled with lualatex %
\documentclass{beamer}
\begin{document}
\begin{frame}
Test
\end{frame}
\end{document}

Thanks in advance and best wishes,
