Python升级提示Tkinter模块找不到的解决方法

一、安装tkinter
在Linux中python默认是不安装Tkinter模块，
代码如下:
[root@li250-193 ~]# python
Python 2.6.6 (r266:84292, Feb 22 2013, 00:00:18)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named Tkinter
>>>
我们安装Tkinter模块
代码如下:
[root@li250-193 ~]# yum -y install tkinter
...
[root@li250-193 ~]# python
Python 2.6.6 (r266:84292, Feb 22 2013, 00:00:18)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>>
二、升级Python
Linux的Python版本默认都不叫低
查看Python版本
代码如下:
[root@li250-193 ~]# python -V
Python 2.6.6

DOWN新版本
代码如下:
[root@li250-193 ~]# wget http://www.python.org/ftp/python/2.7.4/Python-2.7.4.tgz

解压安装
代码如下:
[root@li250-193 ~]# tar -xf Python-2.7.4.tgz
[root@li250-193 ~]# cd Python-2.7.4
[root@li250-193 Python-2.7.4]# ./configure
...
[root@li250-193 Python-2.7.4]# make
...
[root@li250-193 Python-2.7.4]# make install
...

看看新版本Python是否可以使用Tkinter？
代码如下:
[root@li250-193 Python-2.7.4]# ./python
Python 2.7.4 (default, Apr 12 2013, 08:03:09)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter      
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/root/Python-2.7.4/Lib/lib-tk/Tkinter.py", line 39, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter
>>>

提示找不到tkinter模块？看看旧版的是不是正常
代码如下:
[root@li250-193 Python-2.7.4]# python
Python 2.6.6 (r266:84292, Feb 22 2013, 00:00:18)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>>

旧版的没问题，难道需要yum install tkinter一次？
代码如下:
[root@li250-193 Python-2.7.4]# yum install tkinter
