Problem with compiling gcc (LFS 7.0)

i have problem with compiling gcc !!
here is what i did:
i extracted gcc-4.6.1.tar.bz2 ,then i extracted mpc,mpfr and gmp.and put them in the gcc directory:
gmp(extracted directory)-->gcc-4.6.1
mpfr(extracted directory)-->gcc-4.6.1
mpc(extracted directory)-->gcc-4.6.1

the i changed my directory to issue this command:
patch -Np1 -i gcc-4.6.1-cross_compile-1.patch
to patch the package
after that:
.configure \
--target=$LFS_TGT --prefix=/tools \
--disable-nls --disable-shared --disable-multilib \
--disable-decimal-float --disable-threads \
--disable-libmudflap --disable-libssp \
--disable-libgomp --disable-libquadmath \
--disable-target-libiberty --disable-target-zlib \
--enable-languages=c --without-ppl --without-cloog \
--with-mpfr-include=$(pwd)/../gcc-4.6.1/mpfr/src \
--with-mpfr-lib=$(pwd)/mpfr/src/.libs

with this command i got the MAKEFILE.but when i want to make it:
.
.
.
.
checking sys/time.h usability... yes
checking sys/time.h presence... no
configure: WARNING: sys/time.h: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: sys/time.h: proceeding with the compiler's result
checking for sys/time.h... yes
checking for an ANSI C-conforming const... yes
checking for size_t... yes
checking whether time.h and sys/time.h may both be included... yes
checking for creal in -lm... yes
checking for __gmpz_init in -lgmp... yes
checking for MPFR... no
configure: error: libmpfr not found or uses a different ABI.
make[1]: *** [configure-mpc] Error 1
make[1]: Leaving directory `/mnt/lfs/sources/gcc-4.6.1'
make: *** [all] Error 2

where did i do wrong,guys?

Did you follow the directions exactly? These commands are issued AFTER you unpack gcc and then cd into the gcc-4.6.1 directory

Code:

tar -jxf ../mpfr-3.1.0.tar.bz2
mv -v mpfr-3.1.0 mpfr
tar -jxf ../gmp-5.0.2.tar.bz2
mv -v gmp-5.0.2 gmp
tar -zxf ../mpc-0.9.tar.gz
mv -v mpc-0.9 mpc

I can't tell if that's what you did based on your description. Also, since you didn't tell us, I am assuming you are working on section 5.5.
