groovy rosserial does not recognize the location of the sketchbook

edit

Ubuntu 12.04 groovy

I have installed the rosserial by using the instructions at github.com/ros-drivers/roserial and followed the catkin instructions

cd catkin_ws catkin make catkin make install source ~/catkin_ws/install/setup.bash cd /home/charlie/sketchbook/libraries rosrun rosserial_arduino make_libraries.py

everything seems to work OK up to this point, then I get the following statement

"make_libraries.py generates the Arduino rosserial library files. It requires the location of your Arduino sketchbook/libraries folder"

Arduino is installed on the desktop.

Any ideas ?
