    Please `brew unlink #{conflicts.map(&:name) * " "}` before continuing.

    Unlinking removes a formula's symlinks from #{HOMEBREW_PREFIX}. You can
    link the formula again after the install finishes. You can --force this
    install, but the build may fail or cause obscure side-effects in the
    resulting software.
