[NETFRAME] Still get warnings

[Nemesis]

Hi dudes,
while i run a script that takes packets from the Net::Pcap and then
show me the main fields of each error, i get the following warnings:

Name "Net::Frame::Layer::AO" used only once: possible typo at
/usr/local/lib/perl5/site_perl/5.10.0/Class/Gomor.pm line 57.
Name "Net::Frame::Layer::AA" used only once: possible typo at
/usr/local/lib/perl5/site_perl/5.10.0/Class/Gomor.pm line 56.
Name "Net::Frame::Simple::AO" used only once: possible typo at
/usr/local/lib/perl5/site_perl/5.10.0/Class/Gomor.pm line 57.


Why ?
