[CentOS] xulrunner-devel dependencies

What's the deal with all of the new dependencies for xulrunner-devel in
the last update?  I'm updating my servers and the update for
xulrunner-devel is forcing me to install 43 new packages!  Is this a
packaging problem, or are all of those packages really needed?

For the moment, I've been removing xulrunner-devel from my machines to
avoid the problem.  I figure since it is a development package, I can
always reinstall it later if I need it.
