Salam :)

I have the latest version of node.js installed on ubuntu 12.04, I'm not behind any proxies, and my network settings are correctly configured, and were intact since last time when NPM worked fine. But now NPM hangs up installation of any modules with following error:

nasser@nasser-desktop:~/projects/server v3$ npm install simple-proxy
