It might be overkill to use gdb for debugging a script. After all, you aren't debugging perl yet, are you? You could try to force the script to tell you where it got stuck via alarm: 
#!/usr/bin/perl -w

use strict;
use Carp;

$SIG{'ALRM'} = \&debug;

alarm 5;
sleep 1;
sleep 1;
sleep 1;
sleep 1;
sleep 1;
sleep 1;
sleep 1;
sub debug {
    confess "here I got stuck:";
    exit 1; 
}
__END__
here I got stuck: at alarm.pl line 17
        main::debug('ALRM') called at alarm.pl line 13
        eval {...} called at alarm.pl line 13
