problems installing samples from unicms

Hi
I installed lenya 2.0.3 and tried to download the samples from UNICMS  
following
the instructions in http://wiki.apache.org/lenya/HowToMoreExamplePublications 
.

I copied them to $LENYA_HOMEbuild/lenya/webapp/lenya/pubs, restarted  
lenya
and I see the new publication unicms in the page. But when I click on  
it, I get the
error:

/root/lenya-2.0.3/build/lenya/webapp/lenya/pubs/unicms/config/ 
publication.xml (No such file or directory)

org.apache.cocoon.ResourceNotFoundException: Resource not found. at

cause: java.io.FileNotFoundException: /root/lenya-2.0.3/build/lenya/ 
webapp/lenya/pubs/unicms/config/publication.xml (No such file or  
directory)


What am I doing wrong?
