Error when yum install ganglia on CentOS 5.8

 I was doing a yum install of Ganglia on CentOS 5.8,

# yum install php rrdtool ganglia ganglia-gmetad ganglia-gmond ganglia-web httpd

I got the error as below. 

ganglia-web-3.1.7-3.el5.rf.x86_64 from rpmforge has depsolving problems
  --> Missing Dependency: php-gd is needed by package ganglia-web-3.1.7-3.el5.rf                                                              .x86_64 (rpmforge)

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

To avoid the error during the installation, see Installing and Configuring Ganglia on CentOS 5.8
for more information.

Step 1, install the libdbi.so.0(64bits) package

1. Make sure you have the RPM Repositories installed. For more information, see Useful Repositories for CentOS 5
2. Make sure installed the libdbi-0.8.1-2.1.x86_64.rpm for CentOS 5.9 be installed on the CentOS 5.8. Apparently, there is no conflict or dependency issues. See RPM Resource libdbi.so.0()(64bit)

   # wget 
   ftp://rpmfind.net/linux/centos/5.9/os/x86_64/CentOS/libdbi-0.8.1-2.1.x86_64.rpm

   
   

   # rpm -ivh libdbi-0.8.1-2.1.x86_64.rpm

3. Install PHP 5.4. See Installing PHP 5.4 on CentOS 5
4. Finally do the 

# yum install php rrdtool ganglia ganglia-gmetad ganglia-gmond ganglia-web httpd

5. For the rest of the steps do look at Installing and Configuring Ganglia on CentOS 5.8
