      raise <<-EOS.undent
        The version of Freetype that comes with Leopard is too old to build
        MuPDF against. It is possible to get MuPDF working on Leopard using the
        Freetype formula from Homebrew-Alt and some tweaks to the Makefile.
        This is left as an exercise for the reader.

    system "make install prefix=#{prefix}"

    # MuPDF comes with some handy command-line tools. However, their names can
    # clash with other tools installed by formulae such as Poppler. So, we
    # add a `mu` prefix to every binary that starts with `pdf`.
    bin.entries.select{ |b| b.basename.to_s.match /^pdf/ }.each do |p|
      mv bin + p, bin + ('mu' + p.basename.to_s)
    end
  end

__END__

Remove some Makefile rules that Homebrew takes care of through CFLAGS and
LDFLAGS. MuPDF doesn't look at CPPFLAGS, so we piggyback it onto CFLAGS.
