qt_gui_cpp error when installing indigo on rp2

edit

I'm trying to install ROS Indigo on RP2 but when I do the step 2.3 (Building the catkin workspace) as in the tutorial it freezes every time at that point. Is somone know why it happens? http://wiki.ros.org/ROSberryPi/Instal...

==> Processing catkin package: 'qt_gui_cpp'

==> Building with env: '/opt/ros/indigo/env.sh'

Makefile exists, skipping explicit cmake invocation...

==> make -j4 -l4 in '/home/pi/ros_catkin_ws/build_isolated/qt_gui_cpp'
