Trying to use LuaFileSystem on Ubuntu 10.04

I've installed LuaFileSystem using the command: luarocks install luafilesystem. Now I want to use it in my script but I get this error:

[splay.sandbox] W: Require of lfs refused 10:34:11.65 (6) [splay.events] E: thread: 0x93f0b20 DIE (error: [string "job code"]:35: attempt to index local 'lfs' (a nil value)) 10:34:11.65 (6) [splay.events] E: stack traceback: 10:34:11.65 (6) [string "job code"]:35: in function 'getHomeDirectory' 10:34:11.65 (6) [string "job code"]:79: in function <[string "job code"]:76>

I've tried to declare it global: lfs = require"lfs", or just require"lfs", even local in a function:

function getHomeDirectory(position)
    local lfs = require"lfs"

    print(lfs.currentdir())
end

But still I get that error. There's something that I still have to do to make it work?

LATER EDIT: the same error with "a nil value" I get when trying to open a file with io:

local f = io.open('/home/alex/Desktop/SPLAY WORK/splay_client_commands_1.4/test1.txt', "r")

[splay.events] E: thread: 0x955f4c0 DIE (error: [string "job code"]:120: attempt to index local 'f' (a nil value))

What could be the problem?

The io.open call can be easily debugged by adding assert around it. This will print the error message when io.open fails to open the file:

local f = assert(io.open('/home/alex/Desktop/SPLAY WORK/splay_client_commands_1.4/test1.txt', "r"))

This "trick" is also described at: http://www.lua.org/pil/21.2.html
