npm error when starting etherpad-lite the first time on OpenSuse 12.3

hope you can help me. I am trying to install etherpad-lite on OpenSuse 12.3. Etherpad version 1.2.11 I also tried to install nodejs from source and then running it but it did not work. I now use node version 0.8.12 und npm version 1.1.63.

I get the following error: http://imageshack.com/i/n1s83nj

Thanks for any help ;)

npm

You need internet connectivity to grab the dependencies. Try connecting to the Etherpad and trying to install Etherpad again.

Realize this is old, but for posterity thought I'd share what I did to get Etherpad installed behind a firewall. I installed Etherpad on a system with internet access, and then zipped up the directory and compiled on the system with no internet.
