I have exactly the same problem. No nss-devel is installed currently. But yum update always gives the below message: ... Package nss-devel.i386 0:3.12.2.0-2.el5.centos set to be updated ... nss = 3.12.2.0-2.el5.centos is needed by package nss-devel ... I can't install nss-devel either due to the very same error. Sorry Michael, I still haven't figured it out. No clue at all. Mufit
