Yes, that's been a problem for a while. The main issue is that FF is at the
top of a large tree of dependencies, and we've still been working through
them making them build with current sources and compiler. We haven't got
there yet - I don't know if there are any roadblocks or simply that nobody's
had the time to go through them all (or by the time you finish the list the
first ones were broken again by upstream).

That's why I'm trying to get them in continuous integration so we can keep
track of breakages more easily - but the autobuilder dependencies don't map
so easily into Jenkins config.
