Compiling gcc-4.5.0 : error with ppl

[Preeti Sharma]

I am trying to compile gcc-4.5.0 which requires ppl (among other things) .
I already installed gmp, mpfr, mpc . But ./configure on ppl gives me
the following error :

checking for the GMP library version 4.1.3 or above... no
configure: error: Cannot find GMP version 4.1.3 or higher.
GMP is the GNU Multi-Precision library:

Although gmp 5.x is installed and the LD_LIBRARY_PATH is set.

Possible problem statements in config.log are :

configure:4096: checking whether we are actually using the Intel C compiler
configure:4123: gcc -c   conftest.c >&5
conftest.c:11: error: expected '=', ',', ';', 'asm' or '__attribute__'
before 'me'
