I didn't comment on this section before since the program seems to have had very little effort put into it. The last if !line; part will never do anything even if corrected since $line is only declared and assigned a value if the regex matches.

  my $line = $_ if /\bWood\b/;
    chomp ($line);
    last if !line;

Perhaps something like last if /^\s*$/ placed ahead of the my $line = $_ ... would work.
