Permission denied in make installworld

[Pat Maddox]

I'm upgrading to 5.3-p7, and the buildworld, buildkernel, and
installkernel all went fine.  Now when I try installworld, I get this
error:

lalas# make installworld
mkdir -p /tmp/install.Zzqwwvov

*** Error code 126

That error shows up on two different machines I use, using the same
upgrade procedure.  Any ideas on what to do?
