dig.pl that comes with the modules has some problems.
It passes all the $config values as undef if they are not supplied on
the command line.
Instead of what it does now the $config hash should be filled only
with values that were actually
supplied by the user.
attached version is fixing the issues.
-------
I downloaded the dig.pl that comes with the module using
wget http://api.metacpan.org/source/MIKER/Net-DNS-Dig-0.12/examples/dig.pl
and tried to run it:
$ perl dig.pl perlmaven.com
unsupported Proto '' at
.../perl-5.18.2/lib/site_perl/5.18.2/Net/DNS/Dig.pm line 680.
Then I edited dig.pl, commented out
#Proto => $tcp,
and ran again:
$ perl dig.pl -t ns anymaven.com
; <<>> Net::DNS::Dig 0.12 <<>> -t ns anymaven.com.
;;

;; Got answer.

OTOH
$ dig -t NS anymaven.com
; <<>> DiG 9.8.3-P1 <<>> -t NS anymaven.com
;; global options: +cmd

After commenting out all the other values in
my $config = {
#Timeout => $time,
#PeerAddr => $server,
#PeerPort => $port,
##Proto => $tcp,
#Recursion => $recurse,
};
it started to work:
$ perl dig.pl -t NS anymaven.com
