Yum problem (fedora-core 2)

[Omri Schwarz]

Hi, all, 

I am trying to bring a Fedora Core 2 test machine (x86_64)
to make itself a fully updated Fedora Core machine, non-test. 

Yum refuses to do it, complaining as follows:

Resolving dependencies
.conflict between glibc-common and glibc
conflict between glibc-common and glibc
conflict between tzdata and glibc-common

The RPM versions are:
# rpm -q glibc
glibc-2.3.2-11.9
glibc-2.3.3-18
# rpm -q glibc-common
glibc-common-2.3.2-11.9
glibc-common-2.3.3-18
# rpm -q tzdata
tzdata-2003d-2

What can I do to get rid of this annoyance?
