Not Getting Modules folder in mod_cluster final gz version

Hi,

I have downloaded "mod_cluster-1.2.0.Final-linux2-x64-ssl.tar" from community site. But modules directory is not present once I un-tar it.
Can You please let me know from where I can get the modules directory including the *.so files those are required to configure cluster.
