you must be speaking of the ARTWORK, which was "optional"
most likely what happened was WGET never retrieved the SRPMS from the redhat servers....
this actually happened to me so much that i put my own files up, and had my own private script i ran instead of that one.
in a perfect world my script would work fine, but perhaps the redhat servers don't like people downloading their artwork?
at any rate.... you can easily fix your problem by either reinstalling the standard centos artwork packages.... or by running a modified script... such as the one below.
*note that the only difference is where the SRPMS are downloaded from...
sorry that you ran into problems.... but hey at least they weren't related to the actual ISPCONFIG portion....
i threw the artwork stuff on there as a bonus...
*note that this script will work... NOW... but i might be moving my server soon, and at which point you'd have to download the files from somewhere else....
the easiest thing for you might be to just download the files manually, and comment out the parts in the script where WGET is used....
