UnsatisfiedLinkError means that the JVM can't find a native method,
and Solr and Lucene have no native methods.  Something else is
probably messed up...

Try building and running Solr with the supplied lucene jar first, to
make sure you have the process down correctly.  Once that works, then
try moving to the latest lucene jars.
