The ifplatform package contained in dev-texlive/texlive-latexextra-2010-r1 is incompatible with LuaTEX and should be updated: *snip* Package ifplatform Warning: I can't tell if this is Windows or *nix; you appear to be neither. *snip* See the PDF on: http://www.ctan.org/tex-archive/macros/latex/contrib/ifplatform *snip* If you ever see the error I can’t tell if this is Windows or *nix; you appear to be neither. then I’d dearly like to know how it happened. It should never occur, as far as I know. (Update: in previous versions of this package, this message appeared when running under LuaTEX.) *snip* Replacing ifplatform.sty with a recent one solved the issue.
should be fixed in -r2, thanks
