Install netscape (download link here)
The error message that you will get: libstdc++-libc.1-1.so.2 is not found
sudo apt-cache search libstdc++
You’ll see a package libstdc++{version number here}-glibc2.2
sudo apt-get install libstdc++{version number here}-glibc2.2

Create a symlink to the so netscape is looking for:
sudo ln -s libstdc++-lib6.2-2.so.3 libstdc++-lib6.1-1.so.2
