I did a checkout earlier today and a deployment install with 'run -i' as instructed in the run script. The only change I made to caldavd.plist was to change the HTTP port from 80 to 8008 -- a port not otherwise in use. When I try to start the server I get this: # caldavd -X -R caldav_kqueue exec python /usr/bin/twistd --reactor=caldav_kqueue -n caldav -o Twisted/reactor=caldav_kqueue /Library/Python/2.5/site-packages/calendarserver/tap/caldav.py:48: DeprecationWarning: mktap and related support modules are deprecated as of Twisted 8.0.
