How to Diagnose Weatherreport from CouchDB

After building CouchDB from github. I run weatherreport as recommended in documentation to get the following error. How do you diagnose exactly whats going wrong? 17:38:27 WARN: 'escriptize' command does not apply to directory /home/test/workspace/CouchDB-ant_rhel/couchdb 17:38:27 [ * ] Setup environment ... ok 17:38:27 [ * ] Ensure CouchDB is built ... ok 17:38:27 [ * ] Ensure Erlang boot script exists ... ok 17:38:27 [ * ] Prepare configuration files ... ok 17:38:27 [ * ] Start node node1 ... ok 17:38:28 [ * ] Check node at http://127.0.0.1:15984/ ... ok 17:38:28 [ * ] Running cluster setup ... ok 17:38:30 [ * ] Exec command bin/weatherreport --etc dev/lib/node1/etc --level error ...
