Ben, i think, i know what is going on. Can it be that you did NOT use the flag "-r oacs-5.2" when you checked out oacs from the CVS archive, so you got CVS HEAD? This would explain, why you got the request monitor with the throttle message AND why you could not install xowiki.
- the xowiki definition says that it depends on file-storage 5.1.0
- oacs 5.2.2 contains file-storage 5.2.0d8
- CVS HEAD contains file-storage-5.1.0a17
- apm version compare says that 5.1.0a17 is older than 5.1.0
CVS Head is not supposed to work.
