In general, where capistrano, maven, and others fail is providing integration with the sysadmins’ tools. Most of those tools try to recreate a dev-centric environment on every system, rather than promoting and enforcing reproducibility in any environment.

Plus, allowing rpm and yum to handle dependency resolution means that your code can have dependencies on packages provided by the distro without requiring your devs and sysadmins to document this multiple times in multiple locations.
