Potato source.list

[Dean Struss <destruss@rconnect.com>]

Hi all,
 Am taking the plunge to potato using apt-get dist-upgrade
and the one source I have in /etc/apt/sources.list is:
http://http.us.debian.org/debian potato main contrib non-free
I've already received 10 error 404 file not found, so I'm asking
what else I should put in sources.list.
The files not found are:
ldso 1.9.11-8
gcc 1:2.95.2-10
cpp 1:2.95.2-10
libstdc++2.10-dev 1:2.95.2-10
g77 1:2.95.2-10
gobjc 1:2.95.2-10
g++ 1:2.95.2-10
libstdc++ 2.10 1:2.95.2-10
libace 5.0.7-2
libgpm1 1.17.8-16
