Run "helloworld" error as ROS user

Hello,
I run HelloWorld as the orocos components maual tell.
first $ rosrun ocl orocreate-pkg HelloWorld # ... for ROS users,,,,,this step  
is no problem.
Then  $ cd HelloWorld
       $ make
I got a message.
Linking CXX shared library libHelloWorld-transport-corba-gnulinux.so
make[3]: Leaving directory `/home/human/HelloWorld/build'
[100%] Built target HelloWorld-transport-corba-gnulinux
make[2]: Leaving directory `/home/human/HelloWorld/build'
make[1]: Leaving directory `/home/human/HelloWorld/build'

I throught I have already create HelloWorld application.
then I Create an 'helloworld.ops' As the manual told.shows below.
require("print") // necessary for 'print.ln'
import("HelloWorld") // 'HelloWorld' is a directory name to import
print.ln("Script imported HelloWorld package:")
displayComponentTypes() // Function of the DeploymentComponent
loadComponent("Hello", "HelloWorld") // Creates a new component of type  
'HelloWorld'
print.ln("Script created Hello Component with period: " + Hello.getPeriod() )

I run the $ deployer-gnulinux -s helloworld.ops -linfo
I got an error.

0.268 [ ERROR  ][DeploymentComponent::import] Failed to import components,  
types or plugins from package or directory 'HelloWorld' found in:
0.268 [ ERROR  ][DeploymentComponent::import]  
HelloWorld:HelloWorld/gnulinux:/home/human/HelloWorld:./HelloWorld

0.286 [ ERROR  ][DeploymentComponent::loadComponent] Unable to create Orocos

0.286 [ ERROR  ][ScriptingService] HelloWorld.ops :Parse error at line 6:  
Service or Task "Deployer" has no Peer or Service Hello (or Deployer was not  
found at all).

Then I run that.
Deployer [S]> cd Hello
It told me No such peer:  Hello

So how can I figure it out.thanks a lot^_^
