When I > perform 'port distfiles gmp' I get: typing `./contrib/download_prerequisites` and then rm isl rm gettext in the source directory is too much work? you don't need to do any configure etc. GCC's build system knows how to do it when you build them in-tree. IFF you want to use the MP GMP et al. then you will need to add the --with-gmp= etc back into your configure options .. and there we are going back to more external deps and failing to simplify.
