I have build-essential installed, and when i apt-get libmpfr/libgmp3_2 (or whatever they're called) it is reportedly already installed.. ?
It's just a guess, but error says it needs GMP 4.2 or higher, and name libgmp3_2 would suggest it's GMP 3.2 (or other from 3.X line), so it's too old... maybe try running "apt-cache show libmpfr" and other packages to check their versions and see if it really is >=4.2 for gmp, >=2.3.1 for mpfr and >=0.8.0 for mpc... if it is, there still might be some path-related issues, maybe the configure cannot find the libs if they are in non-standard paths?
