Ouch, yes, I have seen this happen before.

rpm -e packagename-version-release

(ie: just put the whole version there...)

So, this was partially upgraded. Just glibc and not the other glibc*
packages.

I don't remember exactly what I did in a similar situation. "glibc"
could be tricky because without it pretty much nothing will work (I
think). Backup your stuff and have a recovery cd handy...

After writing the stuff below[*] I looked again at "man package-cleanup"
and found it has a "--cleandupes" option that supposedly will erase
older versions of duplicated packages. I have never tried to use it so I
don't know if it is the best option, specially for something like glibc.
I imagine it could do the right thing and then you could try another
upgrade...

[*] This is what I was writing before:

You could try with some other not-so-critical package first. From your
list of duplicated packages. 

Take one of the dups, say you have:
  goo-1.2-3
  goo-1.3-2
So try to:
  rpm -e goo-1.2-3
And after that verify that the remaining package has what it is supposed
to have:

rpm -V goo

You should get no errors from that. But it may be that goo-1.2 and
goo-1.3 shared some exact same files in which case I think they will be
missing (not sure about this). Then you need to reinstall goo... I don't
see a way to force a reinstall using yum (it will probably tell you you
already have it installed if you try). 

There may be some other easier way to do this I don't know about...
[anyone else in the list with "repair experience"?]
