xorg 7.2 install and remote ssh

Hello list, I did an xorg 7.2 upgrade
(My way is to pkg_delete -a then do a lot of pkg_add -r  on package-6-stable)

The upgrade was ok. But I was unable to invoque an X client
remotely via ssh.

Sympthom : ssh -v fail wiith a message "debug1: Remote: No xauth
program; cannot forward with spoofing."

I did little research :
e:~/>strings /usr/bin/ssh |grep xauth
../..
/usr/X11R6/bin/xauth
../...

Oh damnit ssh is not aware that /usr/X11R6 is now /usr/local ! :-(
Bug ?

Turn around:  cd /usr/X11R6/bin/; sudo ln -s /usr/local/bin/xauth
