just run yum update on our servers,64 bit servers no problem, all OK, but 32 bit servers (redhat enterprise 5.2) all have the following error. Do I just need to find the missing package and install, will solve this? Thanks for any advice.

I have had this happen before. go to the centOS repos and download + install the packages that it is complaining about in order.
try yum again after each install...

I just want to install the first missing package(ghostscript),also getting error...

actually the package is already there
[root@ctddev ~]# rpm -qa | grep ghost
ghostscript-fonts-5.50-13.1.1
ghostscript-8.15.2-9.4.el5

solved
it's a bug of the package
