Package php-mcrypt.x86_64 0:5.1.6-5.el5 will be installed

Pay attention to the el5, it means that this package is pulling from the EL5 repo. Make sure that the epel-release-6-5.noarch.rpm has been installed successfully:

$ rpm -qa | grep epel
epel-release-6-5.noarch

and the mirrorlist (in /etc/yum.repos.d/epel.repo) point to the right path:

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

(epel-6 instead of epel-5)
