emerge virtualbox之后，运行不了亚。。

bijianing

我emerge virtualbox了已经，
# emerge app-emulation/virtualbox-bin
emerge 到virtualbox-bin的是后，提示要手动下载，我照提示做了，然后又
# emerge app-emulation/virtualbox-bin
提示成功
*
* To launch VirtualBox just type: "VirtualBox"
*
* You must be in the vboxusers group to use VirtualBox.
*
于是我运行：
# VirtualBox
/opt/VirtualBox/VirtualBox: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
这个提示是怎了呢，
谢谢帮忙，
