gfortran 4.7.0 fixes this one.
However, sometimes I get the following:

/home/vitti/gcc-4.7/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/f951:
symbol lookup error:
/home/vitti/gcc-4.7/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/f951:
undefined symbol: mpfr_get_z_exp

Never got this one, I have mpfr-3.0.0-4
How can I fix it?
