I try to install the Capybara-Webkit gem with a bunch and after following the instructions: https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#macos-sierra-1012
I continue to work with a Makefile error that is not found. I updated Homebrew, the gem system, and updated Xcode 8 with cli tools to no avail. It would be very helpful to help!
