Release 0.13.1 missing hwi-war file

Starting the Hive with --service hwi option:

$opt/hive/latest: hive --service hwi
ls: /opt/hive/latest/lib/hive-hwi-*.war: No such file or directory
14/09/22 11:43:46 INFO hwi.HWIServer: HWI is starting up
14/09/22 11:43:46 INFO mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog
14/09/22 11:43:46 INFO mortbay.log: jetty-6.1.26
14/09/22 11:43:47 INFO mortbay.log: Started SocketConnector@0.0.0.0:9999

When navigating to localhost:9999, it just shows the directory index. Looking at the distribution, the war file is missing in the lib directory.
