OK, got it. And the modular BB support I wrote will not immediately help
you. As this is not the use case I had. But it is a use case I want to
support eventually. If you haven't already, you should look at the BB
built-in external Boost lib support <
https://github.com/boostorg/build/blob/develop/src/contrib/boost.jam>. I
haven't used it so I can't claim any suitability. But it does implement the
tagging search for built libs part.

Anyway.. I can try and help in your efforts on getting BPL built this way.

So to answer your earlier questions.. The direction to take is something
like that boost.jam support. I.e. to refactor the parts of boostcpp.jam
that could be hoisted into BB/contrib and then they could be used without
duplication. Of course it's harder to come up with a nice interface for
such things :-)
