如果我在我的OS X Lion 10.7.4上使用“sudo easy_install pip”，那么如何干净地卸载它？
安装后，我还执行了“pip install --upgrade setuptools”命令。
以下是输出结果：

brew install python时会导致符号链接问题，因为它将自己的pip安装到了/usr/local/bin目录下。lrwxr-xr-x 1 usr admin 30 3 3 23:26 pip -> ../Cellar/python/2.7.6/bin/pip
lrwxr-xr-x 1 usr admin 31 3 3 23:26 pip2 -> ../Cellar/python/2.7.6/bin/pip2
lrwxr-xr-x 1 usr admin 33 3 3 23:26 pip2.7 -> ../Cellar/python/2.7.6/bin/pip2.7
我知道可以使用brew link --overwrite python命令，但是如果我不使用easy_install安装的pip，它会留在我的系统中。我更喜欢保持我的系统干净。
有人能解释一下这些警告是什么意思吗？我知道它们不会造成任何损害，但我很好奇是否缺少任何依赖项？
谢谢。
