That looks about right.

Right.  I'm unhappy about having multiple partially
overlapping ways of tracking library dependencies,
but it's good enough for this release.

zlib to boost-install.  In the long run, it's probably
best to generalize boost-install and pull it into Boost.Build.
I'm not sure how feasible that is, though.
