Looks like sonic317-22.consmr.mail.gq1.yahoo.com
Sorry. Looks like you were the victim of using the same IP
as a recent attacker. Filters against yahoo are short lived.
I've cleared it for you. :)

Thanks for all your work here, Mark.
I ran a grep -RF against /usr/src to get some clues. I discovered
much the same as you. It appears the missing file is created during
the build process. But apparently not, in my case.. I clobbered /usr/obj
after my last reply in hopes it was an incidental read/write hiccup.
But the build failed. While the missing file was reported as the cause.
The error was slightly different. At this point I'm inclined to simply
grab a fresh copy of src and try this again. I'll report my findings in
a couple/three hours when it should then be complete.

Thank you again, for all your time and efforts here!
