I guess the answer is: I won't be supporting any beta versions of Domino. If you wish to try to compile ACLHelp on R7 then I would be interested to hear your experiences. I'm not sure why you chose Fedora either. Nice system I'm sure, but not likely to be one supported by Domino. Sorry to disappoint, but time is short and there are many platforms and versions of Domino out there. I'll do my best to support major platforms and versions, but if you want anything else - well it is open source code, so you can always try to compile it on your own system/version.
Best wishes, Ian
