A Linux-based system relies on a single package management tool used
throughout the system. There are multiple helpers for building packages
compatible with that tool but these are just that - helpers, integration glue
which basically boil down to the same scripts, configs, etc. which are
compatible with that underlying packaging tool. Take dpkg and debhelper as an
example. The latter provides a multitude or perl scripts which help building
packages from very different sources but you have to deal with stuff like
debian/control anyway. And this toolset doesn't even begin to solve the
problem of building the dependencies of the package - this task is solved on a
higher level with something like OBS or Launchpad. And to top that, this whole
infrastructure is basically Linux-specific - a portable system with similar
capabilities is a different story (ryppl?).

The bottom line is that the choice is already made on the Linux distro level.
The same would happen on Boost level. Only someone would have to write that
packaging tool and all the integration glue. Or just take and use something
that already exists.
