Questions about install on RHEL 6.2 64bit

Hello,

I am trying to install opManager to RHEL (Redhat Enterprise Linux) 6.2.
This is what I downloaded: ManageEngine_OpManager_64bit.bin. I read the install instructions here
http://www.manageengine.com/network-monitoring/installing_opmanager.html#linux_install

and I found that majority of these packages:
XFree86
XFree86–libs
XFree86–base–fonts
XFree86–xfs
fontconfig
freetype–devel
compat–libstdc++
XFree86–compat–libs
compat–libs

are not supported by RHEL 6.2. (mainly which starts with XFree86)
My question: is there an easy way to install these packages on my system?
I already configured EPEL repo but XFree86 is not included in EPEL as well.

Thanks in advance,

Andras
