I suppose you will have write permissions to that dir. Try installing it in /home/your_username/bin , or /usr/local/bin . Btw, why don't you try via SUSE's package manager? I'm not familiar with that distro, but it have to have such.

Before you run the command to install it, type "su", and you will be asked for a password. Type the password for the root account, and it will give you another shell prompt, only this time, you'll be logged in as root. As root, you should have permission to practically every directory.
