I don't get the error on my system, but I do have xetex installed.
First step in debugging would be

/usr/bin/pandoc hoge.md -s -t latex -o hoge.tex

then run lualatex directly

lualatex hoge.tex

and inspect the log for further messages.

The error message seems to be coming from the ifxetex.sty package,
which defines \RequireXeTeX.  I ran lualatex on hoge.tex and inspected
the list of packages it opened, then grepped through all of them for
\RequireXeTeX.  The only hit was in ifxetex.sty.  So that is no help.

It is possible that the issue you're seeing is cleared up in TeXLive
2011, or maybe in the transition from pandoc 1.9.1.1 to 1.9.1.2.
Sorry I can't be more help at the moment.
