Not quite that simple. You can't just pin the program itself, you also have to pin its dependencies. Which means you have to run ldd to get the libraries it loads (whether directly or transitively), and copy those too, and then you patch the program and its dependencies to set the rpath to $ORIGIN/my/own/directories, then you have to examine all the other more subtle application-level gotchas (e.g. path search order for config files, hard-coded absolute paths, etc.) and port those too. Once you're done, congratulations! You've done 50% of the work of a package manager.
