I have RHEl 5.4 server . Can any body say a link where can i find the rpm list for RHEl 5.4 version. In net i was not able to find these two rpms. Does anybody has this version of rpm file.
krb5-devel-1.6.1-36.el5
gcc-4.1.2-46.e15
You don't say if you have a paid subscription for RHEL, but if you're willing to get by on the CentOS packages (which are functionally identical), the 5.4 archive is at http://vault.centos.org/5.4/os/x86_64/CentOS/ , which includes the versions of the packages you seek.
Unless they've changed the licence conditions, I doubt you will find the RHEL binaries floating out and about, as no redistribution of the binaries is a condition of the RHEL licence.
rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
yum install krb gcc
