        - CPAN Testers Reports from Chris WIlliams identified a very odd error
          with the installed versions of File::Temp and File::Path. Specifying
          versions of both in pre-requisites to ensure known working copies
          are installed.
        - if log file not writeable, ignore audit logging.

          this is something to do with the data format of the image files, but
          to curtail further (already lengthy) investigations, I have written
