You start by going to blackboard and writing "configure does not exist"

Look at generated Makefile -- it has a command to invoke bjam. Copy-paste
that, and add your options by hand.

You should be able to do

  bjam <.....> dll-path=<your-prefix>

See 

        http://www.boost.org/boost-build2/doc/html/bbv2/advanced/builtins/features.html

for a list of things you can specify, which includes dll-path.
