First building the system does indeed solve all xorg package problems. Second I 
am not sure I agree with your statement. I think the answer is relatively easy:
(1) build packages against the base release, or, (2) document the problem, or 
lastly (3) have the port management tools check for this.

While I am not sure if (3) is possible, I am pretty sure (2) is.

Anyway X and its successor Xorg is at once the great leveler and I have learned 
more about FreeBSD getting my Desktops going than any other single activity. I 
appreciate all the time you spent leading me to the solution. Bouncing thoughts 
and ideas with you was most helpful.

I wanted to post my original comment and this to make explicit that a version 7
package will not necessarily work on a 7.2 system. I certainly do not have the 
knowledge to know what system libraries a port is built on. This was actually 
quite easy to find because of the error. If there is no error you are left doing 
a ktrace or something. By the way have gotten the error and figuring out that 
libc was involved, I did not understand the implication, I had help there.
