Probably not related to your problem, but checking $@ is unreliable. Switch to 
eval {
    $data = gunzip( $gz );
1 } or {
    say "Can't unzip $file: $@";
    exit 1
};

See Bug in eval in pre-5.14 for more details.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
