nagios3 and nagios3-cgi 3.5.1.dfsg-2.1ubuntu1.1

If install nagios3 package and then view Alert History, Notification History or Events pages (and maybe others), e.g.:

http://localhost/cgi-bin/nagios3/history.cgi?host=localhost

Then get this error:

Error: Cannot open log file '/var/log/nagios3/nagios.log' for reading!
