see attached ... runs ok on my machine with latest context beta and 
latest luatex beta ... the tracker tells context to create an mp file too

that will give pretty large files as there's a lot going on at the tex end

Hans

ps. given mp development and the fact that context adapts to the latest 
mp and luatex it's best to run the minimals from the contextgarden; 
these can be installed alongside texlive
