Ошибка при компиляции простого кода на C ++

Я пытаюсь скомпилировать этот код cpp на osx lion, но получаю сообщение об ошибке.

#include <iostream> 

using namespace std; 

int main (int argc, char *argv[]) 
{ 
    for(int i = 0; i < 10; i++) 
    { 
        cout << "hi"; 
        cout << endl; 
    } 

    return 0; 
}

Для компиляции:

cc main.cpp

Ошибка:
