wget http://download.ag-projects.com/EventletTwisted/eventlet-0.9pre.tar.gz
tar -xf eventlet-0.9pre.tar.gz
cd eventlet-0.9pre
sudo python setup.py install
cd ..

# python-xcaplib
if [ -d python-xcaplib ]; then
        cd python-xcaplib
        darcs pull -a 
        sudo python setup.py install
else
        darcs get http://devel.ag-projects.com/repositories/python-xcaplib
        cd python-xcaplib
        sudo python setup.py install
