The compiler defaults are set by the package managers that know what work and what do know.<div><br></div><div>Running an OS as old as snow leopard you are likely to find a lot of ports that cannot use the now very outdated system compiler with the OS and need to use a macports supplied one, and one of the clang compilers is generally used here, given the fact clang is the system compiler in more recent OSes. Gcc is not recommended to compile c++ sources, for a number of reasons.<br><div><br></div><div>Just go with what macports wants here.
