Probably the latter.

Are you sure that your src tree is complete? Have you checked out your
src tree with svn? What's the output of 'svn st' and 'svn info'? Have
you tried with a clean /usr/obj? What commands do you use to build
world/kernel?

To include/exclude modules from the build you have to set
MODULES_OVERRIDE or WITHOUT_MODULES. This is explained in
make.conf(5).
