Setting X11BASE

[Andrea Venturoli]

Hello.
I'm trying to do security updates on a few hosts of mine, but nothing 
(portsdb, portupgrade, ...) will work, with the following reason.

 >On FreeBSD before 6.2 ports system unfortunately can not set default 
 >X11BASE by itself so please help it a bit by setting 
 >X11BASE=${LOCALBASE} in make.conf.
 >On the other hand, if you do wish to use non-default X11BASE, please 
 >set variable USE_NONDEFAULT_X11BASE.

I know of the X.Org 7.2 update, but I'm trying to avoid that, since this 
are text-mode servers, and I only have xorg-libraries-6.x as a 
dependency of other ports.

Before I do something really bad, I thought I'd ask:
should I really set X11BASE=${LOCALBASE} or should I set X11BASE=/usr/X11R6?

In case in the future I do upgrade X.Org, should I remove that?

  bye & Thanks
