dublin-traceroute: Failed: Malformed packet

Thanks for working on this project!

I installed via brew install 'https://raw.githubusercontent.com/insomniacslk/dublin-traceroute/master/homebrew/dublin-traceroute.rb' and am seeing the following error when trying it out:

$ sudo dublin-traceroute google.com
WARNING: you are running this program as root. Consider setting the CAP_NET_RAW
         capability and running as non-root user as a more secure alternative.

Let me know if I should provide more information.
