After installing SCTP support on Linux, are you sure you reran configure
for your Erlang/OTP build and then recompiled?

On ubuntu 12.04 I have SCTP working just fine with Erlang R16B02, with
these packages installed:

$ dpkg --get-selections | grep sctp
libsctp-dev install
libsctp1 install
lksctp-tools install

Perhaps you're missing the dev package?
