Bus error in p5-Net-Patricia while starting amavisd

Hi,

Didn't follow the advice "If ain't broken, don't fix it" and regret it. 
I upgraded Perl from 5.40 to 5.42, following the path recommended in 
UPDATING:

[root@numenor ports]# portupgrade -vf -o lang/perl5.42 lang/perl5.40
[root@numenor ports]# portupgrade -vf $(pkg shlib -qR libperl.so.5.40)

Since then amavisd wont start, crashing in p5-Net-Patricia :

[root@numenor ~]# su - vscan
$ amavisd   -c /usr/local/etc/amavisd.conf foreground

Abort trap (core dumped)

The function where it crashes is :

sub add {
   croak "add: wrong number of args" if (@_ < 2 || @_ > 4);
   my ($self, $ip, $bits, $data) = @_;
   $data = (defined $bits ? "$ip/$bits" : $ip) if (@_ < 3);
   my $packed = inet_pton(AF_INET6, $ip);
   croak("invalid key") unless (defined $packed);
   $bits = 128 if (@_ < 4);
   $self->SUPER::_add(AF_INET6, $packed, $bits, $data); <====== HERE
}

I already reinstalled Perl5.42 ans shlib dependencies, with no success.

My interfaces are properly configured for ipv6 :
