Ubuntu11.10 环境下： 在执行 bundle update 或 bundle install 的时候，安装 sqlite3 出错，错误日志如下，大意是所缺少一个本地扩展插件的头文件 sqlite3.h，不知道要怎么解决啊？？？

sqlite3.h is missing.** Try 'port install sqlite3 +universal'
or 'yum install sqlite-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

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