Processing 1.1, sun-javac 1.6.0_20 on OpenSUSE 11.2

Whatever I try, I always get the message:
The package "controlP5" does not exist. You might be missing a Library.

and

Note that release 1.0, libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

To prevent errors I tried with the ready made code from http://www.sojamo.de/libraries/controlP5/examples/ControlP5bang/ControlP5bang.pde

ControlP5 Bang

and some more from that link.

So I have a couple of copies of the library in
processing-1.1/libraries/
controlP5/
with the two subdirectories src and  library

and a copy in scetchbook/libraries/controlP5/
with src and  library
and additionally src and librariy in the directory scetchbook/libraries/.

I tried
import controlP5.*;
and
import processing.controlP5.*;
and
import processing-1.1.controlP5.*;
as well.


What did I wrong?

Thanks
