glibc32 package is not included directly in the ISO compose file for RHGS-3.1-RHEL-6. Further investigation of ISO compose logs, brings out how its getting pulled-in to the ISO by some other RHEL packages. Added glibc.i686 for glibc-common.x86_64 Added glibc.i686 for nss-softokn-freebl.x86_64 Added glibc32.x86_64 for glibc.i686 The feasible solution is to forcefully remove this explicitly from the next ISO.
