I actually use linuxbrew and don't use macs at all. Specifically, the way I like to set up my dev environments is to use Gentoo for the root filesystem, but also throw in linuxbrew to balance compile-from-source purism with binary-package pragmatism for packages and usecases where I just don't care as much about where my packages came from and how they were compiled. One of the things I like about brew is that I can just tarball-up /home/linuxbrew/.linuxbrew and if I get myself into a pickle, I can just unpack a tarball in that location and be up-and-running. After I make any meaningful set of changes to the environment that I'm developing against, I make a versioned tarball and keep it for all eternity, that way I can have reasonable hope that if I ever want to run code I wrote a long time ago and haven't used for a long time, I will be able to re-create the development environment that I was using around it.
