ubuntu11.10 搭建安卓开发 启动eclipse是adb报错！

环境搭建完事了，可是一打开eclipse,就出现   

[2011-11-09 10:44:00 - adb]/home/crazeit/android-sdks/platform-tools/adb: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
[2011-11-09 10:44:00 - adb]'adb version' failed!

[2011-11-09 10:44:00 - adb]Failed to parse the output of 'adb version'



     麻烦高人帮忙解决下，自己第一次在ubuntu上搭建安卓开发环境！谢谢！
