32bit Snow Leopard libc++11 dylibs

[Steven via macports-users]

Hi Guys,I was wondering if anyone has a c++-11 dylib tarball/dmg for me to 
include with my 32bit app so it will run on older Mac OSX ? I'm not super 
technical about Mac stuff, but I should be able to install_name_tool my exe to 
use it... Any other instructions?Thanks Steven Atkinson
