Yersinia Requires Libnet 1.1.2

[Acid-J6]

Trying to install Yersinia on Mac OSX 10.13.3.

Getting an error:
configure: WARNING: Ouch!! At least Libnet library version 1.1.2 is needed in order to compile Yersinia!!...

brew install Libnet
libnet 1.1.6 is already installed

I have tried to search Brew for an older version of Libnet but it only seems to contain the version I have installed.

I can't seem to replicate this. I'm running macOS 10.12, so not sure if that makes a difference. What's the full output for brew install sidaf/pentest/yersinia?
