I looked briefly at the documentation and it seemed like a complicated
solution to a simple problem. It is designed to handle packages which are
not supposed to be installed together. But different versions of dynamic
libraries are designed to be installed together, that's why they have
version number embedded in filename, so they don't need to have each its
