This and every other tmux manager.. written in ruby or some other high level lang.. idiotism. These should be C or Go or whatever lang without shitloads installation required for these.
Think for a second who the target market is: developers. Many, many developers nowadays have a Python or Ruby environment already set up, or both. I'm not even a developer and I run Python, Ruby, and Node utilities without much added complexity.
Plus, the whole point of a decent package manager is to simplify the "shitloads installation" process. Then again the situation might be better on Mac, where Homebrew installations have maybe one or two dependencies, then on your typical Linux distro which will install dozens of libraries separate packages. But then the difference is purely psychological, and that's why commands like "yum autoremove" exist.
