Haha, I caught that part as well (about the exclusivity "fix"). I was
just curious why the error is there in the first place because, after
all, everyone should want SCTP support, right ;-) ? I didn't know
that any Linux distro had lksctp-tools installed by default, but the
module not loaded... learn something new every day though.

So there's two issues (exclusivity not working as expected and then
the SCTP failure if you actually wanted SCTP support) and I'm
concerned about the one that most of you are not, I'm guessing ;-).

I'll try to look at the other problem too though...
