Even the linux-like application package managers for OS X work better than the originals. I never had any trouble with Darwin Ports.
I'm not saying linux is bad. It's a good thing and it's improving. I'm just saying OS X is easier and more friendly.
and don't tell me i did it wrong. that's beside the point. i used google for a while. i still didn't figure out a pleasant way to install a rails environment. that's way too hard.
