 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

 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.

 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.
