I mainly care about having working binary packages, actually.
I want our users not to think that packages disappearing is the norm.

The Debian sitation works for them. While building, they only need
to have one -dev package installed, then the resulting binary package
won't conflict with any other version of boost.

Since pkgsrc always installs unversioned .so links, we need to actively
avoid conflicts.
