If Daniel won't be able to quickly help you through
email, perhaps come over before the meeting tomorrow?
This type of problems is much much easier to debug
face to face in front of actual screen. (I know it might
be enough to look into it after the meeting, but I want
you to have enough time tomorrow to go through a number
of iterations (if needed), so that your environment
is fully set up by the end of the day.)

thanks,
Jacek
