It should work...try turning on debug information with "o debug all".

Update: to be more specific, do:

cpan> o debug all
cpan> b Bundle::Snapshot_2004_01_08_00
[download]

Just to clarify, you should have the snapshot as file: /home/root2/.cpan/Bundle/Snapshot_2004_01_08_00.pm

Is the that file there?
