[CentOS] yum install to a portable location

I have googled, read the man page, and such.

What I am trying to do is install applications to a NFS mounted drive, 
where the libraries and everything are locally installed on that 
filesystem so that it is portable across servers (I have over 100 
servers which each need specific applications installed via yum and we 
do not want to install 100 copies).

We tried the yum relocate and it was not available on Centos6.4

and
yum --nogpgcheck localinstall R-3.1.0-5.el6.x86_64

I want the binaries and all dependencies in the application filesystem 
which is remote mounted on all servers.

Thanks,
