 i saw this on sparc64, too.  i thought it was the old sparc vs pthreads
 vs.  bind issue, and disabled pthreads in bind and it make my bind work
 again.  i have a small patch to the bind build to fix the
 NAMED_USE_PTHREADS=no setting again i plan to commit once i've confirmed
 it doesn't break anything else.  (see below)
 
 in my case, i didn't get to starting named because dhcpcd tried to run
 "dig" which never exited for me, and my boot hung there.
 
 
 .mrg.
