mike hi, it looks like this has been solved, and i leave it in your
capable hands to sort out xulrunner - the question remaining is: what
to do now about hulahop?  i've been asked to help get hulahop into a
working state, but xulrunner 10 is so badly borked that that's
impossible.  that would be fine, if it wasn't for the fact that
xulrunner-dev has now overwritten and replaced xulrunner-9-dev, making
it impossible to now compile up python-hulahop.
