how to install depth image laser scan on fuerte

edit

hi guys, i'm trying to install depthimage_to_laserscan stack by writing

git clone "git link that i cannot post"

cd depthimage_to_laserscan

rosmake

[ rosmake ] rosmake starting...
[ rosmake ] No package specified. Building ['depthimage_to_laserscan']

[ rosmake ] Summary output to directory
[ rosmake ] /home/d4n/.ros/rosmake/rosmake_output-20130420-144925

but it says

then trying to "rosrun"

rosrun depthimage_to_laserscan depthimage_to_laserscan image:=/camera/dept/image_raw

says:

[rospack] Error: stack/package depthimage_to_laserscan not found

I don't know what I'm doing wrong

I know that probably could be a simple things that I forgot to do.

thank a lot for any help

EDIT 1: thanks everybody

i tried as suggested

cd ~/my_ros_directory_thats_in_ROS_PACKAGE_PATH

git clone -b fuerte-devel https://github.com/ros-perception/depthimage_to_laserscan.git

rospack profile

rosmake depthimage_to_laserscan

it results

Failed to invoke /opt/ros/fuerte/bin/rospack deps-manifests depthimage_to_laserscan [rospack] Error: package/stack depthimage_to_laserscan depends on non-existent >package sensor_msgs

then following this http://answers.ros.org/question/12715/how-do-i-install-sensor_msgs-package/

the shell tell me

ros-fuerte-common-msgs is already the newest version.

so, I will migrate to groovy or there is still something to try?

EDIT 2: after a lot of trying I move to groovy and the stack work pretty well.

Thanks for helping me
