Subject Re: "Scheduler with name 'Cocoon' already exists."

hi lars

i had the same problem - seems to be a problem in the cron-block of the 
actual version.

if you don't need the cron- and the scratchpad-block you can exclude 
them from the build.

you can do this by copying to, 
open the latter and uncomment the two lines "include.block.cron=false" 
and "include.block.scratchpad=false"
