gs upgrade failed

[twang <twang@cs.iupui.edu>]

I tried to upgrade gs using apt-get  and I got the following error:

Updating package status cache...done
Checking system integrity...ok
1 packages upgraded, 0 newly installed, 0 to remove and 283 not upgraded.

Need to get 1078k of archives. After unpacking 782k will be used.
Get http://http.us.debian.org slink/main gs [1078k]

I guess the package list is not updated. The version in the frozen (slink) is
gs_5.10-1.deb.
