Hi all I a succeed to install calendarserver on SuSe 10.1 with ./run -s and have no more errors (some of the libraries I had to compile myself) If I try to run it, I get: sudo ./run exec python /usr/local/iCalServer/Twisted/bin/twistd -n caldav -f / usr/local/iCalServer/CalendarServer/conf/caldavd-dev.plist -o ProcessType=Combined Traceback (most recent call last): File "/usr/local/iCalServer/Twisted/bin/twistd", line 21, in ? run() File "/usr/local/iCalServer/Twisted/twisted/scripts/twistd.py", line 27, in run app.run(runApp, ServerOptions) File "/usr/local/iCalServer/Twisted/twisted/application/app.py", line 374, in run config.parseOptions() File "/usr/local/iCalServer/Twisted/twisted/application/app.py", line 354, in parseOptions usage.Options.parseOptions(self, options) File "/usr/local/iCalServer/Twisted/twisted/python/usage.py", line 184, in parseOptions for (cmd, short, parser, doc) in self.subCommands: File "/usr/local/iCalServer/Twisted/twisted/application/app.py", line 365, in subCommands self.loadedPlugins[plug.tapname] = plug File "/usr/local/iCalServer/twisted/plugins/caldav.py", line 9, in getProperty File "/usr/local/iCalServer/Twisted/twisted/python/reflect.py", line 347, in namedObject module = namedModule(string.join(classSplit[:-1], '.'))

Would be nice to get a hint from you. Many thanks, kind regards Roman
