Machine is running much nicer empty, and my backup harddrive died after pulling two things out of it, so clean slate it is.
brew is a command tool for package/ app management under OS X for installing fullapps, dependencies, etc. There's a command
brew leaves that shows just your top-level packages, no dependencies... which is probably worthwhile storing somewhere in case I need to rebuild again.
Update: I've installed some more things and I've parsed the basic
brew list command as well, as some things were missing.
