wurfl on elastic beanstalk

I have setup php environment on elastic beanstalk and uploading code through eb deploy command. EC2 instance is created by auto-scaling group and I can connect it using putty. I want to install wurfl on ec2, I want to know : 1) if I install wurfl on current running ec2 instance, will it get installed on other instance created by auto-scale group ? 2) if not, then how can I install wurfl on beanstalk
