printing to stdout

I'm having issues printing to stdout from lua.  I could have sworn it
was working for earlier cases.  I can read back a value from a
function, but doing a print statement doesn't display anything.  Is
luabind writing to some other location?  I thought I had it going to
stdout when I first set it up...

    // Create a new lua state
    lua_State *myLuaState = lua_open();

    // Connect LuaBind to this lua state
    luabind::open(myLuaState);

    // Define a lua function that we can call
    luaL_dostring(myLuaState,
                  "function add(first, second)\n"
                  "  return first + second\n"
                  "end\n"
                    );

    std::cout << "Result: " << luabind::call_function<int>(myLuaState,
"add", 2, 3) << std::endl;

//luaL_dostring(myLuaState, "_meshImporters = {}");

    // read
    luaL_dostring(myLuaState, "print('test')");
