Today i finally decided to go ahead with installing subversion, after a bit of reading i opened a ssh session and input :
[root@servername ~]# yum install subversion
But to my surprise i got an error 
Error: Missing Dependency: perl(URI) >= 1.17 is needed by package subversion
After a bit of googling i managed to find a solution on a forum and i thought to post it here, maybe other will find it faster 
First we need to download the perl(URI) with version greater than 1.17 using the following command.
wget http://yum.trixbox.org/centos/5/RPMS/perl-URI-1.35-3.noarch.rpm
Then to install the perl package :
rpm -i perl-URI-1.35-3.noarch.rpm
That is it, you can now install and configure subversion as normal.
Cheers.
