I removed the older installation and re-installed the server from  
scratch.  After doing this, using the run -i / command, I still had to  
correct two problems I've had in the past.

1) caldavd - in the caldavd produced the PYTHONPATH defined is

Note the missing initial "/".  Nothing at all works without changing  

2) After fixing the above when running the server it fails.  Reported  
in the error log (or Console I'm not sure) is that it can't find /usr/ 
share/caldavd/bin/twistd.   I grep'd through the code and can't find  
where this is referenced so I fixed it by aliasing /usr/share/caldavd  
to /usr/local.  Then all works just fine.

I'm sure I'm doing something incorrect in configuration or build but I  
can't find where.  (1) seems like a bug but its been like this for
