Can't creake a package on fuerte

edit

I want to run this example. To do, I should create a package. But I can't create the package on ros-fuerte.

There are two ways package build type named catkin and rosbuild. Which one I should?

I tried both of them. My fuerte workspace is under home folder. Using catkin;

fuerte_workspace$ catkin_create_pkg using_markers roscpp visualization_msgs
Created file using_markers/CMakeLists.txt
Created file using_markers/package.xml
Created folder using_markers/include/using_markers
Created folder using_markers/src
Successfully created files in /home/user/fuerte_workspace/using_markers. Please adjust the values in package.xml.

Next step is :

You should be able to build the code with:
 $ cd %TOP_DIR_YOUR_CATKIN_WORKSPACE%
 $ catkin_make

I don't have any catkin workspace(or I can't find it). So, I tried to create a workspace using this [guide].(http://wiki.ros.org/catkin/Tutorials/create_a_workspace). But catkin_init_workspace doesn't work. Error message is fuerte_workspace$ catkin_init_workspace command not found .

How can I create a package on fuerte?

EDIT

I tried rosbuild+fuerte. The guide says that

Before getting started, let's create a scratch package to called using_markers, somewhere in your package path:
roscreate-pkg using_markers roscpp visualization_msgs

I tried roscreate-pkg using_markers roscpp visualization_msgs command, and I got an error. Error mesaage is below :

fuerte_workspace$ roscreate-pkg using_markers roscpp visualization_msgs
