Error in installing latest gcc in centos 6.8

I have followed HDJEMAI suggestion, but when I do 

./configure --with-system-zlib --disable-multilib --enable-languages=c,c++

there is this error:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

but then if I do 

sudo yum install libmpc-devel
Loaded plugins: fastestmirror, nvidia, refresh-packagekit
Setting up Install Process
Loading mirror speeds from cached hostfile
 * base: repos-tx.psychz.net
 * elrepo: repos.dfw.lax-noc.com
 * extras: mirrors.thaidns.co.th
 * rpmforge: mirror.team-cymru.org
 * updates: mirror.mojohost.com
No package libmpc-devel available.
Error: Nothing to do

If I look fo the libraries, I have

ls /usr/lib64/libmp
libmpcdec.so.5        libmpfr.so.1.2.0      libmpssconfig.so
libmpcdec.so.5.0.2    libmp.so              libmpssconfig.so.0
libmpfr.so            libmp.so.3            libmpssconfig.so.0.1
libmpfr.so.1          libmp.so.3.1.14

but notice that there is no libmpfr.a as in here. In that same dirrectory I have libgmp.so.

How do I install libmpc-devel? And then how do I install gcc?

You should use contrib/download_prerequisites in the GCC source directory to download the sources of the dependencies. GCC will automatically build and use them during the build process.

Matching system libraries on Red Hat Enterprise Linux 6 are either missing or just too old.
