i am trying to run the following tutorial:http://winnie.kuis.kyoto-u.ac.jp/HARK/wiki.cgi?page=HARK-ROS+Tutorial+2
but i get the following error and the program stops abruptly:
[ INFO] [1307457046.525074887]: Connected to master at [localhost:11311]
ROS node : HARK_MASTER_NODE generated...
/dev/rtc: Permission denied
Cannot open /dev/rtc
ioctl: Bad file descriptor
node_RosAddHarkIntClient_1 constructor end...
since i was having issues with permissions i tried using sudo and ran the file in terminal,but i get the following error;
ROS_ROOT is not set! Using default rosconsole configuration values
Scanning def /usr/lib/flowdesigner/toolbox

[FATAL] [1307457375.864763327]: ROS_MASTER_URI is not defined in the environment. Either type the following or (preferrably) add this to your ~/.bashrc file in order set up your local machine as a ROS master:
then, type 'roscore' in another shell to actually launch the master program.
[FATAL] [1307457375.864837707]: BREAKPOINT HIT
file = /tmp/buildd/ros-cturtle-ros-1.2.6/debian/ros-cturtle-ros/opt/ros/cturtle/ros/core/roscpp/src/libros/master.cpp
i exported the ROS_MASTER_URI variable in the .bashrc file and started roscore in a new terminal.but the result is same.i still get the same error.Can some one please tell me how to resolve this issue.
