packages missing (different ver) using jigdo

[Leonardo Francalanci <lfrancalanci@simtel.it>]

I'm using jigdo to download the DVD image for the installation.

Some packages have wrong version number, so I get a lot of "404 - not 
found". For example: the package 
/a/alsa-lib/libasound2-doc_1.0.7-4_all.deb doesn't exist (anymore?). I 
suppose the right package would be 
/a/alsa-lib/libasound2-doc_1.0.8-1_all.deb

Why the .jigdo file isn't correct and points to old versions of packages?
