If this is to be useful without major work, you actually need to provide the whole tree, all of the packages. As far as I'm informed, there have been significant changes to the ACS Core data models as well.
It's not allowed to upload more than 2 MB in the storage area. The complete installation has 12 MB as a ZIP file. If you want to have other packages or scripts I can Upload the separately.
Hi Andreas, maybe someone can scp the whole installation to OpenACS.org and provide a download link somewhere. I think this is better than downloading all the packages seperatly.
