Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+
I downloaded GCC 4.5 from http://www.netgull.com/gcc/releases/gcc-4.5.0/ but when I try to setup / build I am getting below error:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ 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.
Linux:>~/shared_scripts/bin/gcc/gcc-4.5.0 1041>
The following libs are present in respective directories
/usr/lib/libgmp.a
/usr/lib64/libgmp.a
/usr/lib/libmpfr.a
/usr/lib64/libmpfr.a
I do not have libmpc.a library installed anywhere in boxes.
Based upon the error how can I know :
a) what is the current version of libgmp.a and libmpfr.a are installed.
b) If they are of incorrect version how can I deploy my own version without disturbing the current one?
Answer
Inside the gcc directory, do this command:
./contrib/download_prerequisites
After that script, GMP, MPFR, and MPC will be ready to use. Continue with ./configure.
