Help: "undefined reference to `PyArg_ParseTuple'" when execising 'Extending Python with C or C++ '

[Lu Jian Xiong]

Hello,
I am a newbie of python.
When I was trying the example read from the following URL,
http://www.python.org/doc/current/ext/simpleExample.html,
it showed the following error message:

[root at localhost user0]# gcc -I /usr/include/python2.2/ -L /usr/lib/python2.2/c
onfig/ -l python2.2 spammodule.c
/tmp/ccIl3dpq.o: In function `spam_system':

#include <Python.h>
static PyObject *
spam_system(self, args)
    PyObject *self;
    PyObject *args;
{
    char *command;
    int sts;

    if (!PyArg_ParseTuple(args, "s", &command))
        return NULL;
    sts = system(command);
    return Py_BuildValue("i", sts);
}
int main()
{
    return (0);
}
[root at localhost user0]#

What is the matter? What should I do?
Can you help me?

Excuse for my poor English.
