Erik,
	As I said before, the tinderbox / exp-run infrastructure needs to be made portable, the infrastructure needs to be there, and as extra credit (I've stated this in other emails in the past) parallelization in ports/pkg_install needs to be fixed as ports/packaging in FreeBSD doesn't work in an ACID[1]-like manner. I'd rather not repeat the reasons in greater detail. Please look for my replies to this thread on current@ for more details in "part A", and look for my replies on ports@ for more details in "part B".
Thanks,
-Garrett
