Nobody knows how to use the package manager. What happens in practice, is every single program uses the the package versions the distro happens to ship with.

If you want a newer version, too bad - your OS doesn't ship that so better luck in the next release. OR you can set up a private repo, and either ship a binary that has the dependencies included (shipping half the userland with your audio player), or they package the newer version of library, which will unwittingly break half your system, if not today, then surely at the next distro upgrade.

It speaks volumes of Linux package management woes, that no vendor ships anything analogous to brew or chocolatey.
