[Koha] Errors when installing CPAN modules on Ubuntu

Hi all, I'm trying to install Koha 3.0 on an Ubuntu Gutsy computer using the instruction found at http://wiki.koha.org/doku.php?id=ubuntu_gutsy Unfortunately I'm getting some errors when installing some of the CPAN modueles (not the ZMARC one). I've attached two text files with the errors. These are the two commands I execute separately: sudo perl -MCPAN -e 'install Class::Factory::Util' sudo perl -MCPAN -e 'install Net::LDAP' Can someone please tell me what I need to do to continue? Thanks Rax
