I got the same error. I did

wget https://raw.githubusercontent.com/insomniacslk/dublin-traceroute/master/homebrew/dublin-traceroute.rb
Then did
brew install --HEAD -s dublin-traceroute.rb

Now it bombs like this

% brew install --HEAD -s dublin-traceroute.rb

Sorry for the multiple posts. I did this and it see
cd /Library/Developer/CommandLineTools/SDKs/
sudo ln -s MacOSX11.3.sdk MacOSX11.0.sdk
brew install --HEAD -s dublin-traceroute.rb
It's installed. Now to figure out how to use it.

Also needed to edit to_graphviz.py to change
print graph
to
print(graph)

and
for flow, hops in traceroute['flows'].iteritems():

to
for flow, hops in traceroute['flows'].items():

I've no clue what I'm doing but this all worked for me.
