Socket type not supported error for IPPROTO_SCTP

Hi all,
This is my first query to this group.

When I try with the following program :
int main(int argc, char **argv)
4 {
5 int sock_fd, msg_flags;
6 char readbuf [BUFFSIZE];
7 struct sockaddr_in servaddr, cliaddr;
8 struct sctp_sndrcvinfo sri;
9 struct sctp_event_subscribe evnts;
10 int stream_increment = 1;
11 socklen_t len;
12 size_t rd_sz;

13 if (argc == 2)
14 stream_increment = atoi (argv[1]);
15 sock_fd = Socket (AF_INET, SOCK_SEQPACKET, IPPROTO_SCTP);16 bzero (&servaddr, sizeof(servaddr));
17 servaddr.sin_family = AF_INET;

SCTP socket is not created and the error generated is "Socket type not supported".

I am using the following kernel version:

(sctpdemo)$ uname -a
Linux titan 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:32:14 EDT 2005 i686 i686 i386 GNU/Linux

Please let me know the following:
1) Should I install any RPM so that SCTP socket type is supported?
2) If RPM is to be installed then please let me know the version of that RPM for the kernel I have and its link where can I get that RPM?
3) Any additional changes that I should make so that the socket is created successfully?

Kindly respond to this query as soon as possible as I am stuck up at first level of SCTP itself.

Thanks in advance,
Praveen Dandin

I am also getting the same error. I have installed the source forge open source for the SCTP. Even the "make v4test" from the sctp source directory is also giving the same error.
