This may be related to the build infrastructure. I've set up my build environment

cd ~/src/trunk
export PEGASUS_HOME=`/bin/pwd`; unset CLASSPATH; . setup-devel.sh

updated to the latest check-out,

svn update

and created a binary distribution file

ant clean dist

However, something in the run-time python path setup must be wrong, because monitord dies on me:
