Dune build suggests running "make" and "make install" or "sudo make install"

When running dune build I get the following output

$ dune build

configuration successful!
now type "make" to build
then type "make install" or "sudo make install" to install

it's especially confusing when running make when building a mirage unikernel to get this message. Perhaps it's enough to redirect the output:
