[SciPy-User] Error when building scipy.0.9.0 - "f951: undefined symbol: mpfr_get_z_exp"

[Xiong Deng]

Hi,

I just find out that the gcc-4.7 is downloaded as a binary distri. I did not
compile gcc-4.7 myself...

The gcc included on my system is gcc 3.4.5 and there seems no gfortran built
on it (However there is a g77 on it, which cause problems while building
numpy/scipy....)...In addition, there are not mpc, mpfr, gmp on it with gcc
3.4.5, so I need a new gcc with gfortran, mpc ,mpfr ,gmp, which is necessay
for numpy/scipy....

Btw: I am not sure if there is a way to install mpc, mpfr, and gmp, after
gcc has been installed and link gcc with mpc, mpfr, gmp...

Many thanks
XIong
