【求教】Arduino 制作电子时钟时，程序运行出错问题！

在使用Arduino设计电子时钟时，程序运行出错，具体问题如下：请求各位吧神帮忙解答，谢谢！
1.打开Arduino-----运行示例文件（文件---示例---DS1307RTC---Settime），然后就是这样的情况！
2.错误提示：

使用 1.0 版本的库 Wire 在文件夹： F:\arduino\5-开发软件\官方标准开发软件arduino-1.0.5-windows\Arduino\hardware\arduino\avr\libraries\Wire
使用 1.4 版本的库 DS1307RTC 在文件夹： C:\Users\Administrator\Documents\Arduino\libraries\DS1307RTC
