'gcc_select mp-gcc46' doesn't work correctly:

$ gcc_select -n mp-gcc46 Selecting version "mp-gcc46" for gcc ln -sf /opt/local/bin/gcc-mp-4.5 /opt/local/bin/gcc ln -sf /opt/local/bin/cpp-mp-4.5 /opt/local/bin/cpp ln -sf /opt/local/bin/c++-mp-4.5 /opt/local/bin/c++ ln -sf /opt/local/bin/g++-mp-4.5 /opt/local/bin/g++ ln -sf /opt/local/bin/gcj-mp-4.5 /opt/local/bin/gcj ln -sf /opt/local/bin/gcov-mp-4.5 /opt/local/bin/gcov ln -sf /opt/local/bin/gfortran-mp-4.5 /opt/local/bin/gfortran
