OK, in :

there were instructions to set in environment (in your case) :

export LD_LIBRARY_PATH=/opt/gcc_4_7_2/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/
export C_INCLUDE_PATH=/usr/include/x86_64-linux-gnu
export CPLUS_INCLUDE_PATH=/usr/include/x86_64-linux-gnu

before 'configure' and 'make' and make a symlink :

sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib64

before 'make install'
