So I'm assuming "options SCTP" is in the kernel config?

I've sent an email to our FreeBSD colleagues so I'll get back to you on 
this.  Just curious but where exactly do you obtain your source from?

I could give you some but first see #5 below...

I saw your config.log and it can't seem to find libsctp.a or libsctp.so... 
can you do a find on a your system to see if these exist?  The same can be 
said about your netinet/sctp.h; these locations need to be pasted into 
--with-sctp, --with-sctp-lib, and/or --with-sctp-include so that LDFLAGS 
and CPPFLAGS can be set appropriately (or you can set them yourself).  Or 
if these files don't exist on your system, we have another problem...

Generally, yes, and come to think of it, I have when building ch3:sctp 
almost exclusively.
