Comment 4 for bug 162310

I mentioned in bug #163139 that miro would need a build depends on firefox-dev. I later compiled and ran miro using the latest version of xulrunner found in Debian and noticed that it ran faster with libxul than from building against firefox-dev, and this was without installing python-psyco. I've attached a patch of the only changes that I've made for building miro-1.0-1.
