You forgot to mention the horribly slow, unreliable and opaque pile of Ruby scripts that users tend to herd these random binaries with.

Or you can use MacPorts, which is rock solid and never borks your machine.

I really don’t know why people use anything else.

I’m not overly fond of MacPorts dependency on the full-fat Xcode instead of just the Xcode CLI tools.

I’d rather have Xcode than something messing with my /usr/bin folder.
