Unable to uninstall or remove package

Hi,

I'm using RHEL 6.3 64bit on server. I need to remove this package audit-libs-2.2-2.el6.x86_64 and change/install audit-libs-2.2-2.el6.i686. However when i executed "yum remove audit-libs-2.2-2.el6.x86_64", the error message appeared at the end of line "Error: Trying to remove "yum", which is protected You could try using --skip-broken to work around the problem, You could try running: rpm -Va --nofiles --nodigest". any idea how to remove this package ?

also, are these depedencies automatically remove by using "yum remove audit-libs-2.2-2.el6.x86_64" ?
[root@SERVER ~]# rpm -qR audit-libs-2.2-2.el6.x86_64
/sbin/ldconfig
/sbin/ldconfig
config(audit-libs) = 2.2-2.el6
