我安装了xcode 3.0。我需要安装sqlite3-ruby gem（用于rhosync）。
当我跑步时：
sudo gem install -l sqlite3-ruby
我收到以下错误：
Building native extensions. This could take a while...
ERROR: Error installing sqlite3-ruby:
ERROR: Failed to build gem native extension.

sqlite3-ruby only supports sqlite3 versions 3.6.16+, please upgrade!

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/sqlite3-ruby-1.3.1 for inspection.

我检查了许多链接（在Stack Overflow和其他网站上），但似乎没有任何效果。
有些人建议从Mac OS X Disk 2安装Ruby Headers。但是我没有那张光盘。我改为安装了XCode 3.0 SDK。
我该怎么办？
