I've been using Homebrew for years and, although I've not had any major problems with it, I do find the slowness irritating. And also the fact it tends to ridiculous bloat by keeping previous versions of everything installed, unless you remember to do some spring cleaning every now and then. I'm up for giving MacPorts a go. But is there a pain-free way to transition between Homebrew and MacPorts, without having to reinstall everything over again? I've installed a load of stuff with Homebrew, over the years and don't fancy having to pick through it all again to try and remember what I installed and why.
