How to remove an i686 pkg without touching x86_64 one?

["Eric B." <ebenze hotmail com>]

Hi,

I've got an RHEL4 x86_64 system that I installed a while ago.  I was doing
some maintenance on it, and noticed that I had two different versions of
glibc installed: glibc.i686 and glibc.x86_64.  The only way I am able to see
the difference between the packages is using rpm -q --query --queryformat
%{ARCH} glibc.

I would like to either remove the i686 version of glibc or at the very least
see which pkgs depend upon it.  How can I check the dependencies on the i686
pkg or remove the specific i686 package without touching the x86_64 one?

Thanks,

Eric
