Centos – php-xml install complains of dependency php-common but this is already installed (CentOS)

How do I force php-xml to see the already installed dependency?

sudo yum install php-xml

complains about:

php-common = 5.1.6-34.el5_8

but running yum install php-common

php-common-5.1.6-34.el5_8.i386 already installed

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems

                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

Update

I have tried the suggested clean-ups and reran the commands. I also ran yum install php-common again, first as it was the dependency then yum install php-common.

Update 2

Tried yum clean all as @Janne Pikkarainen suggested but still failed (I hadn't tried yum clean all but had tried the other things suggested before that)

Then tried re-running the commands, first yum install php-xml – failed, perhaps the dependency first then? so, yum install php-common – already installed as we've seen before, so again yum install php-xml – still failed :-

Update 3

It would appear that the version I have of php-common-5.2.10-1.el5.centos is newer than the one being asked for as a dependency of php-xml, php-common = 5.1.6-34.el5_8

[root@dtsrvishvt2 /]# rpm -qa |grep php
php-ldap-5.2.10-1.el5.centos
php-common-5.2.10-1.el5.centos
php-5.2.10-1.el5.centos
php-mcrypt-5.2.9-2.el5.centos.3
php-pdo-5.2.10-1.el5.centos
php-cli-5.2.10-1.el5.centos
php-mysql-5.2.10-1.el5.centos
[root@dtsrvishvt2 /]#

So how would I force php-xml to use the later verion I already have?

(Spawned off this question and asked separately here: How to force CentOS yum to use a later version of a package dependency already installed (php-common as a dependency of php-xml) )
