Hi
I followed instructions from 
http://advogato.org/person/redi/diary/240.html

so gmp, mpfr and mic were built,  when I issued make for gcc
here is what I did
mkdir <path_to_gcc>/objdir
cd <path_to_gcc>/objdir
<path_to_gcc>/gcc-4.6.1/configure
--prefix=/Users/dima/Development/GCC/builds/gcc-4.6.1/build/x86_64
--enable-languages=c,c++,fortran


however I got the same error
checking for x86_64-apple-darwin11.0.0-gcc...
