rpm reports 2 glibc, what can I do?

[Neal Becker]

I'm trying to debug this:

yum update
.....Unable to satisfy dependencies
Package dbh-devel needs dbh = 1.0.18-1, this is not available.
Package samba needs samba-common = 0:3.0.2a, this is not available.
Package xorg-x11-libs needs xorg-x11-libs-data = 0.0.6.6-0.0.2004_03_11.9,
this                   is not available.
Package glibc needs glibc-common = 2.3.3-18, this is not available.

I found this:
rpm -q glibc
glibc-2.3.3-18
glibc-2.3.3-18

Probably this is the problem.  Obviously, I can't just erase glibc to fix
it.  What can I do?
