It works! Thanks P.J. !

(I did a manual checkout and setup.py install)

I still get 2 deprecation warnings:

C:\Python26\lib\site-packages\trellis-0.7a3_dev_r2610-py2.6.egg\peak\events\trellis.py:4:
DeprecationWarning: the sets module is deprecated
C:\Python26\lib\site-packages\trellis-0.7a3_dev_r2610-py2.6.egg\peak\events\trellis.py:509:
DeprecationWarning: object.__new__() takes no parameters

But I guess that's OK for now. :)

Keep up the good work!
Peter
