Comment (by cal@…):

 It's fine if you need GCC for some specific project. What isn't OK is
 adjusting a symlink in `/usr/bin`, especially because it breaks stuff such
 as this. Please create those symlinks in `/opt/local/bin` instead:

 {{{
 sudo rm /usr/bin/cc
 sudo ln -s clang /usr/bin/cc
 sudo ln -s gcc /opt/local/bin/cc
 }}}

 This way, typing `cc` on the command line will run the same compiler as
 typing `gcc` would (both from `/opt/local/bin`, so your requirement should
 be fulfilled), but the system wasn't changed.
