Hello!

The procedure I went through:

# tar -xvf /path/to/dtrace-20080211.tar.bz
# cd src
# time make buildworld

The system is:
FreeBSD wep4017.physik.uni-wuerzburg.de 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Thu Jan 31 13:04:43 CET 2008     lexx_at_wep4017.physik.uni-wuerzburg.de:/usr/obj/usr/src/sys/GENERIC  amd64

/etc/make.conf contains:
CPUTYPE         ?= nocona

Should I disable building 32-bit compatibility libraries?
If so, how can I do that? I saw some make switch some time ago, but
now I see nothing similar in src/Makefile or src/Makefile.inc1.

The second question, is parallel build with make -jN option supposed to work?

Thanks,
Alexey.
