Well I do have luamplib version 1.04 which avoids this error (it
should be \directlua instead of \luadirect I think) but now gives
another error with luatex and lualatex:

! LuaTeX error j:/MIKTEX2.7/tex/luatex/luamplib/luamplib.lua:74: bad
argument #2 to 'format' (string expected, got nil)
stack traceback:

...ectlua {luamplib.process([[#1]])}
