I haven't really understood how to build a pd_luax file then... nevermind.

mmh sure, I just used that cause that was the part of code frank 
mentionned and thought this was a kind of pd secure-interacting functions.

I manage to get it work with this code:

function LSpell:in_1_symbol(s)
    word = s

    cmd = "echo " .. word .. " | /sw/bin/ispell -a | grep \\*"

    p = assert(io.popen(cmd))

    result = p:read("*all")
    if(string.len(result) ~= 0) then
      self:outlet(1, "symbol", {word})
      end

end

It outputs the word only if it exists in ispell.

Can Lua be used as a more stable shell interpretor for all the functions?
It is of a big interest!!

Thanks to all,

Nicolas
