contrib's build-nsdzones.pl does not work for me

[Stephane Bortzmeyer]

I'm playing with nsd 1.2.1 contrib directory. Trying build-nsdzones.pl
immediately fails:

astrid2:src/nsd/nsd-1.2.1-AFNIC/contrib % perl build-nsdzones.pl --nsdcconf ./nsd.conf --bindconf $HOME/Gouda/named.conf --nsdkeysdir keys --nsdzones ./nsd.zones 
Require of DNS::Config::Statement::Acl failed
Require of DNS::Config::Statement::Acl failed
Require of DNS::Config::Statement::Acl failed

Require of DNS::Config::Statement::Server failed
Require of DNS::Config::Statement::Server failed
Require of DNS::Config::Statement::Server failed
Require of DNS::Config::Statement::Server failed
Require of DNS::Config::Statement::Logging failed

The funny thing is that there is no "require" of anything named Acl or
Server in the code. I assume these names are produced from BIND's
named.conf sections.

The produced nsd.zones is almost empty:

zone    0.0.127.in-addr.arpa            localhost.127.0.0

DNS::Config 0.66
Perl 5.6.0
