Проблема зависимости при установке PostGIS на CentOs 6.3

Я новичок в Linux и пытаюсь установить PostGIS2 после успешной установки PostgreSQL 9.1. Машина работает под управлением CentOS 6.3 и имеет установленную cPanel.

Проблема: Когда я попытался установить PostGIS с помощью yum: yum install postgis2_91 postgis2_91-utils, Я получаю ошибку зависимости ниже.

Как мне решить эту проблему зависимости и установить PostGIS? Спасибо вам большое!
