[CentOS] Missing EL4 glibc update

Seeing upstream has an update for glibc http://rhn.redhat.com/errata/RHBA-2009-0052.html I rebuilt the glibc-2.3.4-2.41.el4_7.1.src.rpm and it produced the following rpms :-

glibc-2.3.4-2.41.el4_7.1.i386.rpm glibc-common-2.3.4-2.41.el4_7.1.i386.rpm glibc-debuginfo-2.3.4-2.41.el4_7.1.i386.rpm glibc-debuginfo-common-2.3.4-2.41.el4_7.1.i386.rpm glibc-devel-2.3.4-2.41.el4_7.1.i386.rpm glibc-headers-2.3.4-2.41.el4_7.1.i386.rpm glibc-profile-2.3.4-2.41.el4_7.1.i386.rpm glibc-utils-2.3.4-2.41.el4_7.1.i386.rpm nptl-devel-2.3.4-2.41.el4_7.1.i386.rpm nscd-2.3.4-2.41.el4_7.1.i386.rpm

Is it okay to install all of them or should i skip the debuginfo rpms? Is an official CentOS update going to be made of the glibc from Red Hat?
