[CentOS] xulrunner dependancy problem

Hi,

Is anyone else noticing a problem updating Firefox and its dependencies?

It appears that xulrunner-devel 1.9.0.6-1.el5 wants xulrunner 1.9.0.5-1.el5,
but "this is not available". Following is the output from Yum when I attempt
to update Firefox on CentOS 5.2 X86_64:
