I'm having problems with ssh.com and X11 forwarding

ssh: SSH Secure Shell 3.2.0 (non-commercial version) on i686-pc-linux-gnu

I am in the process of testing some of my machines with CentOS 5 
x86/x86_64 and have run into a bit of a snag.  X11 Forwarding is not 

I've tried all combinations of (+/-)[Xx] and it doesn't work, seemingly 
it doesn't want to set the environment variable properly and therefore 
doesn't know where to send the X requests.

Any hints?  I've checked the ssh config files and they seem to be 
identical to the config files on our existing SuSE 10.0 machines which 
are working.  This is troubling indeed.
