Nothing else is in the lib directory but this one jar.
Additionally, the logs seem to say that it finds the lib as shown below
INFO: Solr home set to '/home/zetasolr/'
May 20, 2009 10:16:56 AM org.apache.solr.core.SolrResourceLoader
createClassLoader
INFO: Adding 'file:/home/zetasolr/lib/FacetCubeComponent.jar' to Solr
classloader
However as soon as it tries the component it cannot find the class.
