在OS X Lion上与sqlite3 gem挣扎

我是Mac和Ruby on Rails的新手，我正在尝试设置我的环境。 我一直在研究这个教程，并试图在Mac OS X Lion上安装sqlite3 gem。

• Xcode 4.2.1
• git版本1.7.5.4
• Ruby 1.9.3p0
• gem -v结果为1.8.11
• sqlite版本3.7.5

当我尝试运行gem install sqlite3或gem install sqlite3 -- --with-sqlite3-dir=/usr/bin我得到下面的错误文本，有没有人有任何建议？

 Building native extensions. This could take a while...

您将需要sqlite3库文件，我想这应该像运行一样简单

  sudo brew install libsqlite3-dev
