Command line scripts - slf4j

[Ian Dickinson]

If I try any of the command-line scripts from $JENA/jena-core/bin, I get 
an error from a missing slf4j:

ian@ian-desktop $ ~/workspace/jena/jena-core/bin/rdfcat
Exception in thread "main" java.lang.NoClassDefFoundError: 
org/slf4j/LoggerFactory
        at jena.rdfcat.<clinit>(rdfcat.java:215)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
...
I have svn updated and done a mvn clean install in jena-core. What else 
needs doing so that it can find the slf4j dependency?

Thanks,
Ian
