Are you talking about the ‘substitute-keyword-arguments’ part?

I don’t like the above version because it doesn’t allow to choose the
version of GCC.  I’ve attached my version, how can I make it look
better?

Also, ‘/nix/store/nxpzxlvg5z5qq10wzxrzk9hjyhxyicxq-gfortran-4.8.1/bin’
contains these programs:

c++     gcc-ranlib             i686-pc-linux-gnu-gcc-4.8.1
cpp     gcov                   i686-pc-linux-gnu-gcc-ar
g++     gfortran               i686-pc-linux-gnu-gcc-nm
gcc     i686-pc-linux-gnu-c++  i686-pc-linux-gnu-gcc-ranlib
gcc-ar  i686-pc-linux-gnu-g++  i686-pc-linux-gnu-gfortran
gcc-nm  i686-pc-linux-gnu-gcc

Are C++ and C-related programs supposed to be there?
