Cisco is currently funding the port of DTrace to FreeBSD part of their
move to FreeBSD.

I am probably a week away from putting up a set of diffs for the
initial integration into CURRENT. See:
<http://people.freebsd.org/~jb/reasons/reasons.html> for the list
of changes/reasons. That page is still a work in progress.

As of today, the port passes 752 of Sun's DTrace tests.

FreeBSD developers with p4 access can build //depot/projects/dtrace/src
and get an up-to-date CURRENT with DTrace built in. "make universe"
works for all arches. The kernel modules are limited to amd64 and i386
at the moment.
