How can I set up & run PhantomJS on Ubuntu?

I set up PhantomJS and recorded it to video: https://www.dailymotion.com/video/xnizmh_1_webcam Build instructions: http://phantomjs.org/build.html Is there anything wrong in my setup? After I set it up I read the [quick start tutorial][1] and tried to write this code phantomjs hello.js It gives me "command not found" error. How can I solve this problem?
