Struggling with sqlite3 gem on OS X Lion

Question

I'm new to Mac and Ruby on Rails and I'm trying to set up my environment. I've been working through this tutorial and am stuck trying to get the sqlite3 gem installed on Mac OS X Lion.

• Xcode 4.2.1
• git version 1.7.5.4
• Ruby 1.9.3p0
• gem -v results in 1.8.11
• sqlite version 3.7.5

When I try to run gem install sqlite3 or gem install sqlite3 -- --with-sqlite3-dir=/usr/bin I get the error text below, does anyone have any suggestions?

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

您将需要sqlite3库文件，我想它应该和运行一样简单

 sudo brew install libsqlite3-dev
