Quand rrdtool fait des siennes ... sur CentOS

En souhaitant terminer une installation de Cacti et le coupler à Nagios à l'aide de n2rrd, j'ai dû me préoccuper d'installer des prérequis que sont rrdtool et rrdtool-perl.

Seulement, voilà Un petit yum install rrdtool perl-rrdtool me génère cette erreur :
