Xorg problem

[RJ45]

Hello I installed 6.0-RELEASE on Alpha.
But I cannot find the Xorg packages to be installed on the system,
I did a network install.
Now I need Xorg for many reasons and if I Try to install it from the ports 
collection it won't compile because the systems does not have the 
/usr/X11R6/include/X11 needed stuff.
How I can install Xorg ?
Where can I find a pre-packaged one ?
I just would need the include files so I Can compile ghostrscript for 
example.
thanks

Rick
