Hi Daichi,
I wonder which clause/aspect of the license is a problem?
We've been distributing dtrace as part of our source since FreeBSD 7.1 
so the terms of license must have been acceptable for inclusion in our 
tree & redistribution in source for each release since.
I've been reading the CCDL license just now & clause 3.5 on Distribution 
of executable vesions states

You may distribute the Executable form of the Covered Software under the 
terms of this License or under the terms of a license of Your choice, 
which may contain terms different from this License, provided that You 
are in compliance with the terms of this License and that the license 
for the Executable form does not attempt to limit or alter the 
recipient’s rights in the Source Code form from the rights set forth in 
this License. If You distribute the Covered Software in Executable form 
under a different license, You must make it absolutely clear that any 
terms which differ from this License are offered by You alone, not by 
the Initial Developer or Contributor. You hereby agree to indemnify the 
Initial Developer and every Contributor for any liability incurred by 
the Initial Developer or such Contributor as a result of any such terms 
You offer.

This shouldn't pose any legal problems for the project if DTrace was 
redistributed in binary form should it?

I see, was the virtual box issue recently, I'm pretty sure I was able to 
build virtual box on a DTrace enabled system in the past couple of months.
