Just submitted an updated rockspec for version 0.2, which has this separated.

Also fixed the overflow by checking on the Lua side;
  local bitsize = 32
  function M.randomseed(seed)
    seed = math.floor(math.abs(seed))
    if seed >= (2^bitsize) then
      -- integer overflow, so reduce to prevent a bad seed
      seed = seed - math.floor(seed / 2^bitsize) * (2^bitsize)
    end
    if lua_version < 5.2 then
      -- 5.1 uses (incorrect) signed int
      math.randomseed(seed - 2^(bitsize-1))
    else
      -- 5.2 uses (correct) unsigned int
      math.randomseed(seed)
    end
    return seed
  end
