libstdc++-libc6.2-2.so.3

[TheMrOrange]

Hello,
I'm trying to access from Ubuntu laptop to Xubuntu (Xfce) desktop  
connectet by wlan cable using vnc

I've installed vnc in /usr/local/bin using vncinstall but there is an  
error when I run vncserver:

Xvnc: error while loading shared libraries: libstdc++-libc6.2-2.so.3:  
cannot open shared object file: No such file or directory

I can't find a way to install libstdc++-libc6.2-2.so.3

can you help me?
(I've verify hosts are able to ping)

Thanks
Davide
