calendarserver is packaged. So, I cannot run ./bin/develop to install 
new packages. I have gone through the requirements-stable.txt and have 
ensured that all the libraries are at the requested minimum version. 
Does develop script does anything more which I should handle?

Also, the psutil version installed on the system is 3.4.1 while the 
version mentioned in requirements-stable.txt is 2.2.1. So, I went ahead 
and downgraded psutil to 2.2.1 by installing an older debian package and 
the error went away. So, psutil was the cause of the issue. Is it 
possible to make calendarserver compatible with 3.4.1? The 
incompatibility issue seems to be becoming a recurring theme :).

Finally, tasks were still not enabled for the user after the upgrade. 
What do I need to check for this?
