Required Packages For Database Install

Question

I'm installing a new 11.2.0.3 database on RHEL 6.3 64-bit tomorrow and I've got the base installation done and I've followed the following doc. to verify my Linux system has all the appropriate packages however in order to run the OUI (Oracle Universal Installer), I'm told I have to have X11 running on the server and be able to forward the session to my workstation so I can initiate the install over SSH. I just honestly have no idea what the package names or what it is I need to run X11 or X-Windows on my RHEL server. I don't want to install Gnome / X11 since Gnome is completely useless and a huge overhead on a server. I will always run the server in run level 3 (command line interface).
Do you guys know the specific package names or what I need to look for in order to X11 working for OUI?

**UPDATE**
I adjusted the 'oracle' users' DISPLAY environment variable as suggested per the docs and attempted to run the installer again:
[oracle@db1 ~]$ echo $DISPLAY
*localhost:10.0*
[oracle@db1 ~]$ export DISPLAY=local_host:0.0
[oracle@db1 ~]$ echo $DISPLAY
*local_host:0.0*
[oracle@db1 ~]$ cd /u01/app/oracle/database/
[oracle@db1 database]$ ./runInstaller
