This issue seems to be caused by the inclusion of lua 5.2 into new luatex engine. In the end, there should be an update of luamplib package to fix this. For the time being, you can use luatexko-mplib which I uploaded to another mainling list to suggest an adoption into luamplib. Download the attchment at http://tug.org/pipermail/lualatex-dev/2013-April/001504.html and change the line \usepackage{luamplib} into \usepackage{fontspec} \usepackage{luatexko-mplib} then recompile it. I get no error message. BTW, without \usepackage{fontspec}, I get "undefined control sequence" error at \pdfstrcmp. I haven't noticed that before, as I always loaded fontspec package. However, fontspec is a too heavy a package for \pdfstrcmp command only. Could anybody tell me what package is suitable for this purpose? I tried \usepackage{pdftexcmds}, but of no use.
