xorg-server on amd64-current with dtrace failed to compile.

Hello!

I just have got the following error during xorg-server compilation:

> [snip]

The system is:
[wep4017] ~> uname -a
FreeBSD wep4017.physik.uni-wuerzburg.de 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Tue May 13 14:39:16 CEST 2008     lexx_at_wep4017.physik.uni-wuerzburg.de:/usr/obj/usr/src/sys/GENERIC  amd64

Ports are (csup-ed with the system sources, INDEX self-built):
[wep4017] ~> ll /usr/ports/INDEX-8 
-rw-r--r--  1 root  wheel  16377905 May 13 16:56 /usr/ports/INDEX-8

Options for xorg-server are:
[wep4017] ~> cat /var/db/ports/xorg-server/options 
# This file is auto-generated by 'make config'.
# No user-servicable parts inside!
# Options for xorg-server-1.4_4,1
_OPTIONS_READ=xorg-server-1.4_4,1
WITHOUT_HAL=true
WITH_AIGLX=true
WITH_SUID=true




It seems that the problem is clear (xorg-server want unsupported dtrace
provider?). Maybe someone knows how to overcome this situation (build
xorg-server without dtrace support)?

Thank in advance,
Alexey.
