"--with-x=yes (default) and X11 headers/libs are not available"

I am trying to install R in our cluster (the cluster is Red Hat Enterprise Linux 6), where I don't have root access. I tried: $wget http://cran.rstudio.com/src/base/R-3/R-3.1.1.tar.gz $ tar xvf R-3.1.1.tar.gz $ cd R-3.1.1 $ ./configure --prefix=/home/Kryo/R-3.1.1 But I am getting an error: configure: error: --with-x=yes (default) and X11 headers/libs are not available
