As root, run the command 'updatedb' press enter and wit for the command to complete. This will create a database of installed files.
Now run the command 'locate libstdc++.so.6' All commands without the quotes. I suspect the file will not be found.
It is on my system. This is what I see...
If it is not there, go to your package manager, and look for a package with 'libstdc++' in it. Install it, and try again.
