Some folks are successful on Fedora. Did you try the RPM they prepared based on the latest release?
I still can't see what specific difference you have in your setup making it not compatible. You said that it works with Ubuntu - and we don't officially support any other distro, despite trying to assist in porting where we can. Sorry.
