Then you're doing something wrong.

No, but libgmp3-dev, libmpfr-dev and libmpc-dev are available, and if you had
installed them then you would have been able to build gcc a lot more easily. 
It might be too late, if you've installed them yourself and didn't know what
you were doing you might have various broken installations on your system.  Or
they might be fine and you just need to use LD_LIBRARY_PATH.

I suggest you delete the whole gcc-4.5.0 directory, as you might have made a
mess of it. Then either install the gmp, mpfr and mpc dev Ubuntu packages OR
set LD_LIBRARY_PATH to find your existing installations (if you sure they're
installed OK). Then unzip the gcc sources again, but this time follow the
advice at http://gcc.gnu.org/install/configure.html and do not run configure
and make in the gcc-4.5.0 directory:

tar xzvf gcc-4.5.0.tar.gz
mkdir build
cd build
../gcc-4.5.0/configure

Now if it goes wrong you can just remove the 'build' directory and leave the
gcc-4.5.0 source directory untouched.

I'm going to close this bug, since it does seem to be user error not a gcc bug.

Either use LD_LIBRARY_PATH or re-install the gmp/mpfr/mpc libs from your
package manager.

If you still have problems, seek help on an Ubuntu forum or the gcc-help
mailing list.
