You did mention in your OP:

5) Invoke a command to install it

6) Invoke a command to package it (optional)

Maybe you need to be more specific about what you mean in each case. It
sure sounds to me, by the 2 items above, as if you meant to suggest that
you could distribute an individual Boost library ( and its dependencies
) separately from the current monolithic Boost tree. If so, I am
suggesting that without a very well worked out versioning system for
individual Boost libraries such a plan will end up with serious problems
for the end-user.
