      For full Perl support you must install the Image::Magick module from the CPAN.
        https://metacpan.org/module/Image::Magick

      The version of the Perl module and ImageMagick itself need to be kept in sync.
      If you upgrade one, you must upgrade the other.

      For this version of ImageMagick you should install
      version #{version} of the Image::Magick Perl module.
