I am new to Ubuntu, and I was trying to install ns2. ns2 has been successfully installed and while installing nam, I got a segmentation fault:

segmentation fault (core dumped)   

By following some of the instructions in the internet, I am not getting that error and at the same time I am not installed with nam also. When I try to run nam in the terminal, I am not at all directed to it. Should I uninstall that and install it again? If so, how can I do it?
