This means you need to set up your Lua paths properly. See http://www.thijsschreijer.nl/blog/?p=1025

The error you reported points you need the Luarocks installed for Lua 5.1 (Luarocks installs on different paths according to Lua version installed on system)

So...

1. Install lua5.1 on your system
2. After (1) run luarocks instal --lua-version 5.1 luafilesystem
3. Restart your Nginx and try again
