osx python setup.py 无法安装 xattr-0.6.1 应用程序
我刚接触svn和python，但我真的想使用一个更新版本的xattr，这个版本包含比操作系统自带的更有用的功能。
在OSX 10.5.6上，我在安装xattr-0.6.1时遇到了麻烦。
在本地机器的终端中：
$ svn co http://svn.red-bean.com/bob/xattr/releases/xattr-0.6.1/
文件已经下载并放在了~/xattr-0.6.1/这个文件夹里。
$ cd xattr-0.6.1/
$ sudo python setup.py install
---------------------------------------------------------------------------
This script requires setuptools version 0.6c11 to run (even to display
help). I will attempt to download it for you (from
http://pypi.python.org/packages/2.5/s/setuptools/), but
you may need to enable firewall access for this script first.
I will start the download in 15 seconds.
(Note: if this machine does not have network access, please obtain the file
http://pypi.python.org/packages/2.5/s/setuptools/setuptools-0.6c11-py2.5.egg
and place it in this directory before rerunning this script.)

要检查python的版本：
$ python -V
Python 2.5.1
看起来已经安装了python的更新。
我尝试再次运行xattr的安装：
$ sudo python setup.py install

我是不是漏掉了什么重要的基本步骤，或者setup.py的配置有问题，还是说我可能忽略了其他什么？

要编译一个C语言文件，所以需要用到gcc这个工具。对于Mac用户来说，需要安装XCode。更新 正如@jathanism提到的，你应该有一张随你的Mac一起提供的XCode安装光盘（很可能是3.2版本）。
举个例子：
atlas% which gcc
/usr/bin/gcc
atlas% gcc -v
Target: i686-apple-darwin10
..
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5666) (dot 3)
