[fedora7] pb configurationnagios oreon

Bonjour !

Dans le cadre d'un stage, je doit mettre en place Nagios-Oreon.

Mais lorsque je configure avec la commande suivante :

pear install -o -f --alldeps Mail Mail_Mime Net_SMTP Net_socket Net_Traceroute Net_ping Validate Image_Graph Image_GrapViz HTML_Table HTML_QuickForm_advmultiselect Auth_SASL HTTP Numbers_Roman Numbers_Words MDB2 BD_DataObject_FormBuilder BD_DataObject DB Date

Il m'indique les erreurs suivantes :

J'ai pourtant bien installé ces différents packets, mais je ne suis pas sur de leur emplacement.
Pouvez vous m'indiquer quellese erreurs j'ai commises, et comment reégler ce problème ?
Merci d'avance.
