[lltx] luamplib + lualatex

[Troy Henderson]

I must be missing something because when I use the following:

\documentclass{minimal}
\usepackage{luamplib}
\mplibpreamble{ u:=108; }
\begin{document}
	\begin{mplibcode}
		beginfig(1);
			draw fullcircle scaled (2*u);
		endfig;
	\end{mplibcode}
\end{document}

I get the following error(s):
