Howto compile Xorg from source

["Michael D. Norwick" <mnorwick%centurytel.net@localhost>]

Good Day;

I downloaded xsrc.tar.gz from NetBSD-current last night.  I am using a 
freshly built -amd64 kernel, tools, and userland built from the like 
dated src.tar.gz.  The build fails with the following;

gcc -o ssh-askpass -O2 -fno-strict-aliasing -ansi -Dasm=__asm     
-L../../../xfree/xc/exports/lib   drawing.o  dynlist.o  resources.o  
x11-ssh-askpass.o -lXt -lSM -lICE -lXext -lX11 -L/usr/X11R6/lib     
-Wl,-rpath,/usr/X11R6/lib -Wl,-rpath-link,../../../xfree/xc/exports/lib
making all in /usr/xsrc/local/programs/xsystrace...

-I../../../xfree/xc/exports/include   -DCSRG_BASED -D__AMD64__  
-DFUNCPROTO=15 -DNARROWPROTO      -c callbacks.c
callbacks.c:77: error: conflicting types for 'dprintf'

/etc/mk.conf contains;

ACCEPTABLE_LICENSES+=djb-nonlicense
ACCEPTABLE_LICENSES+=generic-nonlicense
ALLOW_VULNERABLE_PACKAGES=YES
MKX11=yes
X11FLAVOUR=Xorg
X11_TYPE=modular

What is going wrong here?  I am referring to at least 2 posted 'howto's' 
googled in the last several days.  I understand that -current is not 
guaranteed to build.  Any help is appreciated.
