Since LuaLaTeX 0.85 (or maybe 0.87) almost all pdfTeX extented primitives with names \pdf have been renamed or removed (see: http://tug.ctan.org/macros/generic/luatex85/luatex85.pdf). <http://tug.ctan.org/macros/generic/luatex85/luatex85.pdf>).
When running LuaLaTeX AMC therefore needs to use \savepos instead of \pdfsavepos, etc.
