(note - I'm not subscribed here...) It seems that the download link for your 2.4 release is broken, as it includes a reference to activemq. Replace that reference to activemq with 'camel', and the URL works.
E.g. the following is broken: http://www.apache.org/dyn/closer.cgi/activemq/apache-camel/2.4.0/apache-camel-2.4.0.tar.gz While this works: http://www.apache.org/dyn/closer.cgi/camel/apache-camel/2.4.0/apache-camel-2.4.0.tar.gz Regards, Upayavira
