Auto bootstrapping just downloads a (somewhat arbitrary) dmd version to
make setup a little easier/predictable, but you should have a dmd
compiler installed on your system, if not:

. $(~/dlang/install.sh --activate dmd)
./src/build.d -v

If your question is about ensuring that DMD is built with the currently
selected version for bootstrapping, you can still do:

./src/build.d -v AUTO_BOOTSTRAP=1
