update packages on red hat without internet connection

Question

I am using Red Hat 6.4 without internet connection. I am trying to install R using CRAN. While I install some dependencies are needed. Some of them are already installed on the server. The issue is when I installed the one of dependency. For example, I need xz version 5.0.3. The server already have xz version 4.9. Is there anyway to update the version of xz? I already tried to install over 4.9 using tar.gz file, but it did not work.
