    On OS X i prefer brew to install SW. Install brew: "github.com/mxcl/homebrew/wiki/installation" then you can install scala or other tools with "brew install scala". And "brew install sbt" Commented Nov 24, 2011 at 11:26

You should add this line to your shell autoload file: .bashrc for bash or .zshrc for zsh.

Sorry. I don't understand. please any code for this? I'm newbie in unix;
If you type echo $SHELL you'll find what shell you're using. If it's bash you'll have to add export PATH="/Users/your_user/scala/bin:$PATH" to your .bashrc file.
