Groovy fail at ./src/catkin/bin/catkin_make_isolated --install [closed]

edit

Hello. I am trying to install ROS Groovy on mac osx 10.8.2 by following instructions from ros.org . Unfortunately after typing ./src/catkin/bin/catkin_make_isolated --install in terminal i get following error:

<== Finished processing package [1 of 153]: 'catkin'
==> Processing catkin package: 'angles'
==> Building with env: '/Users/Slawek/ros_catkin_ws/install_isolated/env_cached.sh'

I tried instructions from here: ---question/51746/groovy-1204-error-on-srccatkinbincatkin_make_isolated-install/ but it didn't work for me

I would like to mention that it is my first installation of ros and I would really appreciate "step by step" instructions.
