Hy man, I finished it, now i'm using ruby 1.9.3 correctly, but my terminal when open always sets down and I have to put it exe c $SHELL, So when I close the terminal and reopen it, I need to put exec $SHELL again to sets it up. I don't know if you will understand me

@nielsenrechia exec $SHELL reloads your current shell and it generally should do roughly the same thing as opening a new terminal. Perhaps these two things are loading different configuration files. Try adding the rbenv init line that is now at the bottom of your ~/.bash_profile to your ~/.bashrc as well.

To install older versions of Ruby (e.g. 1.9.2), I first had to install the official GCC compiler: https://github.com/kennethreitz/osx-gcc-installer/downloads

You should prolly add brew update to the start of the list of commands.

and this could be more sexy-like: brew install rbenv ruby-build rbenv-vars readline ctags

@timoxley Cheers. Updated.

Thank you. Scratching my head for a while. No one else mentioned rbenv-vars.
