Description of problem:
Unable to compile gluster on RHEL6.5 because of gluster dependency on "cmockery2" and "libxml2" packages.
These packages are not available in RHEL repos.
However if we have to compile gluster on RHEL, we will have to enable EPEL Repository by installing the "epel-release" to get the "cmockery2" and "libxml2" packages.
1. wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
2. rpm -ivh epel-release-6-8.noarch.rpm
3. yum install -y libxml2-devel cmockery2-devel
