helloWorld & helloWorldCmd plugins load, not the expected output though

[nyiotis]

I'm testing my new plug-in development environment maya2011, mac os x 10.6.8.
I successfully compile and load the 
helloWorldCmd and helloCmd plug-ins (found in /Autodesk/maya2011/devkit/plug-ins)

When I run

helloWorld

in MEL I get no output (should get "Hello World" based on the helloWorldCmd.cpp) and no error either.

Same result (neither output, nor error) If I go with 

from maya.cmds import *
helloWorld()

in Python. 

Any ideas?
thanks!
