      The graphical user interface is now used when running Octave interactively.
      The start-up option --no-gui will run the familiar command line interface, and
      still allows use of the GUI dialogs and qt plotting toolkit.
      The option --no-gui-libs runs a minimalist command line interface that does not
      link with the Qt libraries and uses the fltk toolkit for plotting.

      EOS

    else

      s += <<-EOS.undent

      The graphical user interface is disabled by default since it is still buggy on
      OS X; use brew with the option --with-gui to enable it.

      EOS

    end

    if build.with? "gnuplot"
      s += <<-EOS.undent

        Octave was compiled with gnuplot; enable it via graphics_toolkit('gnuplot').
        All graphics terminals can be used by setting the environment variable GNUTERM
        in ~/.octaverc, and building gnuplot with the matching options.

          setenv('GNUTERM','qt')    # Default graphics terminal with Octave GUI
          setenv('GNUTERM','x11')   # Requires XQuartz; install gnuplot --with-x
          setenv('GNUTERM','wxt')   # wxWidgets/pango; install gnuplot --wx
          setenv('GNUTERM','aqua')  # Requires AquaTerm; install gnuplot --with-aquaterm

          You may also set this variable from within Octave.

      EOS

    logfile = "#{prefix}/make-check.log"
    if File.exist? logfile
      logs = `grep 'libinterp/array/.*FAIL \\d' #{logfile}`
      unless logs.empty?
        s += <<-EOS.undent

            Octave's self-tests for this installation produced the following failues:
            --------
        EOS
        s += logs + <<-EOS.undent
            --------
            These failures indicate a conflict between Octave and its BLAS-related
            dependencies. You can likely correct these by removing and reinstalling
            arpack, qrupdate, suite-sparse421, and octave. Please use the same BLAS
            settings for all (i.e., with the default, or "--with-openblas").
