首先，到www.python.org去下载最新的3.0版：

wget http://www.python.org/ftp/python/3.0/Python-3.0.tgz
大小11M

tar zxvf Python-3.0.tgz
解压后执行
$./configure
通过
$make
出这么一个错误：
make: *** [sharedmods] 错误 1

查找网上说是locale的问题:

"Python fails
silently on bad locale" bug:
http://bugs.python.org/issue2173

$locale

LANG=zh_CN.UTF-8
LC_COLLATE="zh_CN.GB2312"
LC_CTYPE="zh_CN.GB2312"
LC_MESSAGES="zh_CN.GB2312"
LC_MONETARY="zh_CN.GB2312"
LC_NUMERIC="zh_CN.GB2312"
LC_TIME="zh_CN.GB2312"
LC_ALL=zh_CN.GB2312

是LC_CTYPE的值zh_CN.GB2312不是对Python合法的值，

$ export LC_ALL=zh_CN.UTF-8

$ locale

LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"

LC_ALL=zh_CN.UTF-8

$make
总体成功了，但出如下的错误：

Failed to find the necessary bits to build these modules:
_tkinter
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
这是图形库，可以不管。

$make install

....

* Note: not installed as 'python'.
* Use 'make fullinstall' to install as 'python'.
* However, 'make fullinstall' is discouraged,
* as it will clobber your Python 2.x installation.

安装成功，但没有替换原来的2.x的版本。如果想替换，可以执行"make fullinstall"

执行：

$ python3.0
