  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Error: The Ruby Homebrew installer is now disabled and has been rewritten in

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Then I manually ran /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" and build_support/packages.sh, and everything went well. Seems that the ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"should be replaced by /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

I open PR #451 for this, but I do not know if personal PR is accepted :)
