CentOS - Aug 2013 - minimal X applications needed to export to remote server?

I'm running a piece of network backup software called 'bacula', on a
minimal CentOS 6.4 install.
I got everything working pretty well, but there's one piece giving me some
problem-- a component which gives status info via a GUI.
In the past, on previous installations, I could ssh to the bacula server with
the -X option, and run the application (called 'bat'), and it would
display back.? I'd have to make sure the sshd_config permits Xforwarding,
but that was all.

On my new CentOS 6.4 minimal, I always get:

bat: cannot connect to X server 

I tried the usual tricks of exporting the display to my system where I want to
see the GUI, which shouldn't be necessary anyway due to the 'ssh
-X', but I thought I'd give it a shot.? Still no go.

I figured something was missing, since it is a minimal install, with no X.?? So
I installed 'xlogo', thinking maybe all the X stuff needed to display
that would be installed.? By installing xlogo, I got a bunch of X stuff,
including:

xorg-x11-apps-7.6-6.el6.x86_64

I also have:

libXau-1.0.6-4.el6.x86_64
libX11-1.5.0-4.el6.x86_64
libXrender-0.9.7-2.el6.x86_64
libXcursor-1.1.13-2.el6.x86_64
libXft-2.3.1-2.el6.x86_64
libXxf86vm-1.1.2-2.el6.x86_64
libXi-1.6.1-3.el6.x86_64
libXmu-1.1.1-2.el6.x86_64
libXaw-1.0.11-2.el6.x86_64
libX11-common-1.5.0-4.el6.noarch
libXext-1.3.1-2.el6.x86_64
libXfixes-5.0-3.el6.x86_64
libXdamage-1.1.3-4.el6.x86_64
libXrandr-1.4.0-1.el6.x86_64
libXinerama-1.1.2-2.el6.x86_64
libXv-1.0.7-2.el6.x86_64
libXt-1.1.3-1.el6.x86_64
libXpm-3.5.10-2.el6.x86_64

But I still get the error.

Anyone know which package/rpm/lib I am missing?

Thanks!

Did you try -Y instead of -X?   It has never been clear to me which
things need -Y so I generally just use -Y all the time.  Also adding
-v or -vv to the ssh args will sometimes show the details about what
is failing.  You probably need the xorg-x11-xauth package if you don't
have it.

You've probably already checked, but does the sshd_config deny X11
forwarding?

Did you allow the remote via xhost on your local X server?

Does your desktop require x11 magic cookies or other auth mechanism?

So I installed 'xlogo', thinking maybe all the X stuff needed to display
that would be installed.  By installing xlogo, I got a bunch of X stuff,
including:
You can test by temporarily installing tigervnc-server on the remote
and connecting. If you can run it there it should work remotely.

I'd start out with yum groupinstall "X Window System"

At a minimum I would install xorg-x11-xauth, xorg-x11-tools, xorg-x11-apps,
and xorg-x11-xterm.  Also make sure you configure X11Forwarding to yes in
sshd_config.

I find that I need these additional packages to run gui X-windows apps
from remote systems.

yum install xorg-x11-xauth dejavu-sans-fonts.noarch
