Brew安装git失败

Question

我想用自制软件安装git。 我安装了MacPorts，我从iMac中删除了它。 我也完全删除了自制软件，并用ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"重新安装了它。

在我运行brew doctor我不得不删除（我只是移动它们） /usr/local/lib一些库。 之后我修复了我的.profile的$PATH var，以便/usr/local/bin和/usr/local/sbin覆盖正常的bin目录。

现在我想用brew install git 。 它获取了内容，并开始构建git。 但是在构建期间，它会失败并显示消息

~$ brew install git

我查看了/Users/23tux/Library/Logs/Homebrew/git/ ，它说，有未定义的符号。 这是输出：

Writing perl.mak for Git

HOMEBREW_VERSION: 0.9.3

CPU: dual-core 64-bit penryn
OS X: 10.6.8-i386
Xcode: 3.2.6
X11: 2.3.6 => /usr/X11

（输出更长，我只包括最后几行，错误发生的地方）。

我google了很多，但找不到任何解决方案。 这是因为MacPorts的一些破碎的东西（我知道，他们彼此不喜欢）？ 或者我该如何解决这个问题？

编辑

我刚刚发现，当我正在运行brew doctor ，我得到了这个输出：

You must: brew install git
You must: brew install git
You must: brew install git
Warning: An outdated version of Git was detected in your PATH.
Git 1.6.6 or newer is required to perform checkouts over HTTP from GitHub.
Please upgrade: brew upgrade git

当我运行brew upgrade git我得到Error: git not installed 。 我搜索了我的PATH var以获取任何二进制git（或其他东西），但找不到任何东西。

我认为这意味着，某个地方还有git东西，它与新安装相冲突。 我对吗？

在这种情况下，我无法弄清楚如何使用自制软件安装git。 因为我不想浪费那么多时间，我从这里http://railsinstaller.org/安装了Rails安装程序的整个rvm，ruby，git。 然后它与自制软件一起使用
