problem compliling new kernel for SCTP

[swapnagg at ou.edu]

Iam trying to install SCTP enabled Apache server and Mozilla browser on FreeBSD 6.0  
These are things that i have done:  
  
1) I downloaded the kernel patch from sctp.org and applied it.   
2) Included the line "options SCTP" in MY kernel source code at  /usr/src/sys after making a copy of GENERIC and 
called it MYKERNEL 
3) ran config to generate kernel source code 
 
Problem: 
 
 this gives error, device mfi and device bce are unknown, so i commented out device mfi and device bce.  
 
3) again ran config to generte kernel source code, which was successful. changed into 
the /usr/src/compileMYKERNEL. 
4) Ran the "make depend" command. 
 
Problem: 
Now it gives the following error: 
ERROR(1) 
ln -s /usr/src/sys/i386/compile/MYKERNEL/opt_bce.h opt_bce.h 
ln: opt_bce.h: File exists 
*** Error code 1 
 
Stop in /usr/src/sys/modules/bce. 
*** Error code 1 
 
Stop in /usr/src/sys/modules. 
*** Error code 1 
 
Stop in /usr/src/sys/i386/compile/MYKERNEL. 
 
 
5) Then I copied /usr/src/sys/kern into /usr/include/sys and tried doing "make buildworld" 
 
PROBLEM: 
This gives the following error: 
ERROR (2) 
/usr/src/usr.bin/netstat/mbuf.c: In function `mbpr': 
/usr/src/usr.bin/netstat/mbuf.c:158: error: `MBUF_JUMBOP_MEM_NAME' undeclared (first use in this function)

REQUIRE HELP with the following: 
1) HOw dO i enable FREEBSD kernel with SCTP? 
2) Am i moving in the right direction? Are the steps followed above corect? 
3) How do i get rid of errors (1)and (2)? 
 
I would really appreciate any kind of assistance.
