 I tried with

 {{{
 port install libstdcxx configure.compiler=apple-gcc-4.2
 }}}

 which lead to a somehow familiar error, one that I met when I tried to
 build on Snow Leopard software that would also run on Tiger:

 This -mlong-branch flag is disturbing quite often. How can I build sane
 crt1.o and crt3.o object files for GCC 4.2 with MacPorts?
