Is there a guideline or tool that can help identify how an executable was installed?
I have installed Vim 7.3 long ago (seems called MacVim), and I'd like to upgrade it to 8.0+.
I've tried to list installed packages in some management systems:
port installed (for MacPorts) brew list (for Homebrew) pkgutil --packages (for Installer)
but can't find Vim in any of them.
What should I try further? (Or better a guideline to go through all the popular installation methods/systems)
(For this moment, I may need to uninstall this installation, and use Homebrew to install Vim 8.1 so that I can verify some problems mentioned in somebody's post.)
