smokeping @2.4.2 +Prototype mismatch: sub SNMP_Session::AF_INET6

[filter@…]

I installed smokeping on OS X 10.6.7. Experienced the following error when loading smokeping:

Constant subroutine SNMP_Session::AF_INET6 redefined at /opt/local/lib/perl5/5.12.3/Exporter.pm line 64.
 at /opt/local/lib/smokeping/SNMP_Session.pm line 129
Prototype mismatch: sub SNMP_Session::AF_INET6 () vs none at /opt/local/lib/perl5/5.12.3/Exporter.pm line 64.

Constant subroutine SNMPv1_Session::PF_INET6 redefined at /opt/local/lib/perl5/5.12.3/Exporter.pm line 64.

I forced manual update of Socket6 and NET::SNMP with:

cpan> install U/UM/UMEMOTO/Socket6-0.23.tar.gz
cpan> install Crypt::Rijndael		(a NET::SNMP dependency)
cpan> install D/DT/DTOWN/Net-SNMP-v6.0.1.tar.gz

Reloaded smokeping, and everything works perfectly.

Next, I attempted to install smokeping on an older host running 10.5.x. Experienced the same error when starting smokeping. However, this time, updating Socket6 and NET::SNMP did nothing to resolve the errors.

System details:
OS X 10.5

PERL v.5.12.3
CPAN v1.9600

Relevant installed perl packages:
IO::Socket v.1.31
IO::Socket::INET6 v.2.67
Socket6 v.0.23

Seems like this has something to do with Socket6 naming, but I'll defer to the experts here. If this requires upstream inclusion, please assist, as I am not certain whose shoulder to tap on.

Is this still a problem with the current version?
