Roberto, are you running your servers on Debian potato stable machines? I'm trying to install OpenACS 4 from scratch on my 2.2r2 (granted, with a touch of Progeny) box, and having troubles getting nsxml to compile. It seems that libxml2 needs to be version 2.3.5 or greater, and the current version in stable is 2.2.2. I'll grant you that the libxml2 in "testing" is 2.3.5, but I am trying to avoid installing anything more advanced than "stable" on this particular box.
https://openacs.org/wp/display/77/ is a WimpyPoint presentation where I am trying to document everything as I go along. Comments and suggestions are always welcome!
