I am new to linux and is trying to install PostGIS2 after successfully installing PostgreSQL 9.1. The machine is running CentOS 6.3 and has cPanel installed.

Problem: When I tried installing PostGIS using yum: yum install postgis2_91 postgis2_91-utils, I get the dependency error below.

How should I solve this dependency problem and install PostGIS? Thank you so much!

 You could try using --skip-broken to work around the problem
