It's a warning. It seems unlikely that a minor change to a perl version would
cause a change there. The warning is happening because its testing whether
the first command-line argument is equal to '--version', and there is no
first argument ($ARGV[0]).
Has the exiqsumm script also been updated recently? Its possible that a
newer release has enabled warnings (they're not on by default in perl),
either by adding '-w' to the #!/usr/bin/perl first line, or by adding
"use warnings" somewhere near the top of the script.
