Initial installation errors

[Pranshu Srivastava]

Okay so I migrated to a different machine and npm ied this lib after sudo apt-get install -y build-essential libxi-dev libglu1-mesa-dev libglew-dev pkg-configing the env. The error logs were:

> gl@4.2.2 install /home/rexagod/Desktop/works/is/node_modules/gl
> prebuild-install || node-gyp rebuild
