Hi All

I tried to install ROS in arch following the instructions in http://wiki.ros.org/indigo/Installation/Arch, But the it shows around 247 packages. Not only that if i install the package 1 it fails because ros-indigo-catkin requires python setuptools. I already have setup tools installed. So it spits out the following error. Is it exists then why does it fail ? The log is at the end.

I really need ROS support in Arch Linux so i am ready to work on it during my free time. Can any one tell me whom to contact ? Thanks.

Also Whats the state of python3 support in ROS ?
