[Buildroot] problems linking when using -lSDL

Hi All,
I've recently tried to use SDL with buildroot-2010.11 and crosstools-ng
1.82. I've also tried the latest buildroot snapshot wit a fresh
crosstools. I've managed to have everything working prior to trying to
use SDL.`
've been circling around this for days with no luck. Perhaps someone
can point me in the right direction.
ct.c is a simple hello world which doesn't call in anything
#include <stdlib.h>
#include <stdio.h>
int main () {
printf
("hello world\n");
exit(0);
}
my makefile, though perhaps adding too many directories to searc in
compiles the program properly.
CC = /lfs/x-tools/i586-unknown-linux-gnu/bin/i586-unknown-linux-gnu-gcc
CFLAGS = -Wl,--verbose
LDFLAGS =
LDFLAGS += -L/lfs/x-tools/i586-unknown-linux-gnu/i586-unknown-linux-gnu/sys-root/lib
LDFLAGS += -L/lfs/x-tools/i586-unknown-linux-gnu/i586-unknown-linux-gnu/sys-root/usr/lib
LDFLAGS += -L/lfs/x-tools/i586-unknown-linux-gnu/i586-unknown-linux-gnu/sysroot/lib
LDFLAGS += -L/lfs/x-tools/i586-unknown-linux-gnu/i586-unknown-linux-gnu/sysroot/usr/lib
LDFLAGS += -L/lfs/buildroot/output/host/usr/i586-unknown-linux-gnu/sysroot/lib
LDFLAGS += -L/lfs/buildroot/output/host/usr/i586-unknown-linux-gnu/sysroot/usr/lib
LDFLAGS += -lpthread
ct:
$(CC) $(CFLAGS) $(LDFLAGS) -o ct ct.c
When I add -lSDL to the mix I get a bunch of errors such as:
tools/i586-unknown-linux-gnu/lib/gcc/i586-unknown-linux-gnu/4.4.3/../../../../i586-unknown-linux-gnu/bin/ld: warning: libdirectfb-1.4.so.5, needed by /lfs/buildroot/output/host/usr/i586-unknown-linux-gnu/sysroot/usr/lib/libSDL.so, not found (try using -rpath or -rpath-link)

Any pointers would be appreciated,
