[JDEV] Help with Net::Jabber problem

[g]

With the follwing files:
Net::Jabber::Protocol VERSION 1.26
Net::Jabber::IQ VERSION 1.26

I am getting the following error:
Undefined subroutine &Net::Jabber::IQ called at 
/usr/lib/perl5/site_perl/5.6.0/Net/Jabber/Protocol.pm line 1829.

The line in the Protocol file is:
my $iqAuthProbe = new Net::Jabber::IQ();

Does anyone have a solution for this?
