David sent me logs of the failing case; thanks David!

The failure happens when buildkernel and installkernel are run 
separately instead of all-up, e.g. 'make kernel'.  The installkernel 
step is leaving MK_AUTO_OBJ=no in the env passed to the port build.  It 
looks like at least one of the install stages of nvidia-driver needs to 
generate temporary output, which leads to confusion when the port isn't 
built as though it's an in-tree component.

Can you guys try out the attached patch?
