gdb-6.8 build error with Centos 6

[Needell Gerald]

I am  trying to migrate my RTEMS-4.9 environment from a Centos 5 to  Centos 6  and I can rebuild all of the tools from the source RPM's except gdb-6.8

Am amu using the following configutation:
#! /bin/sh
../gdb-6.8/configure --disable-werror  --with-system-readline --target=sparc-rtems --enable-sim --prefix=/opt/rtems



The build fails with:

ranlib libgdb.a
rm -f gdb
gcc -g -O2      \
		-o gdb gdb.o libgdb.a \
		  ../sim/erc32/libsim.a -lreadline ../opcodes/libopcodes.a ../bfd/libbfd.a  ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a     -lncurses -lm   ../libiberty/libiberty.a

I see that gdb-6.8 is in the prebuilt binary distribution for Centos 6 so there must be a way!

Any suggestions?
Thanks,
