I have put all the jar in the ${solr.solr.home}/lib folder, and now Solr
starts correctly!
There are still warnings, but apparently Solr works

Thanks for this tip.
The original CKAN installation instructions for Solr were for Solr 1.4.1, so
most likely with that version solrconf.xml was simpler and no editig was
required.
I will send the CKAN developers ml the new instructions for configuring Solr
4.5, asking them which Solr components are actually required by CKAN, so
solrconf.xml can be changed accordingly.
Thanks a lot for your precious help!
