ros_lib not created installing arduino [closed]

edit

running a fresh install of hydro on a fresh install of ubuntu Precise. According to the tutorial at http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup

under 3.3 Install ros_lib into the Arduino Environment

"The preceding installation steps created ros_lib, which must be copied into the Arduino build environment to enable Arduino programs to interact with ROS."

ros_lib was not created. any ideas? I rechecked everything in the install, all is well, no error messages etc.

Also, it says to put ros_lib in the libraries folder of the sketchbook. My libraries are at /usr/share/arduino/libraries

Does it matter?
