Error when installing libXi for CentOS 6

If you do encountered an issue such as this. Apparently, there is a incompatibility between llibXi-1.7.2-2.,/pre>2.el6.i686 != libXi-1.6.1-3.el6.x86_64

# yum install libXi 

Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:

         1. You have an upgrade for libXi which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libXi of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude libXi.otherarch ... this should give you an error
            message showing the root cause of the problem.

         2. You have multiple architectures of libXi installed, but
            yum can only see an upgrade for one of those arcitectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.

         3. You have duplicate versions of libXi installed already.
            You can use "yum check" to get yum show these errors. can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).

       Protected multilib versions: libXi-1.7.2-2.2.el6.i686 != libXi-1.6.1-3.el6.x86_64
 You could try using --skip-broken to work around the problem

To resolve the issue, we have to do a

# yum install libXi-1.7.2-2.2.el6.x86_64
and you will see quite a list of updates to some core libraries. Finally, you can do a

# yum install libXi
