apt-get and glibc update

[Federico Grau <donfede@casagrau.org>]

Hello people, 

I am a relatively new debian user (a couple months), but long time 
linux user.  I am curious why the new glibc updates are not showing
up when I run apt-get.

I am running potato, have run apt-get update, and also dpkg -l libc6, 
but the most recent version it lists is "2.1.3-10".  My sources.list 
file is pointing to a local mirror (tux.org)... the announcement and 
new packages were put out a couple days back, could it take that long 
for the mirrors to sync up?

thanks for any feedback,
donfede
