The Centos 6 build failed due to missing dependency "selinux-policy-core"

I tried to build the Centos 6 build with vagrant, in step 5, it failed with the following error message, I am very new in calamari, can any one provide the resolution to solve the problem?

ID: build_deps
    Function: pkg.installed
      Result: False
     Comment: The following package(s) were not found, and no possible matches were found in the package db: selinux-policy-core

     Changes:

Start with the Vagrant CentOS 6 build at step 5 and inspect the build_deps package-installation entry that reports the missing selinux-policy-core package. Verify the package availability in the CentOS 6 package database and define done as completing that build step without the missing-dependency error.
