Thanks for the reply Lowell.  I actually just found the problem that was
causing this just yesterday--when I built this box I'd set up a separate
filesystem for /tmp and had mounted it with various options including
noexec.  After I rebooted into the new kernel, I did a make installworld
without /tmp being mounted, and it worked just fine.  The trick is going
to be to remember this the next time.  ;-)


Thanks again,
Mike
