我在我的 fedora11 机器上安装 mysql 时遇到问题 这是错误的面孔
gem install mysql
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.
/usr/bin/ruby extconf.rb

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.

你有什么想法。
