    [gropdf]: Skip a test if gs unavailable.
    
    * font/devpdf/tests/basic-fonts-present.sh: Skip test if 'gs' command
      not available.  The test is to ensure that gropdf will produce sound
      documents using the base fonts from PostScript, but since gropdf
      requires Ghostscript to do this (as noted in our "./configure"
      messages), it makes no sense to validate font availability if the
      program is absent.  Resolves test failure seen on macOS with minimal
      dependencies installed.
