 Hi Jeremy,

   I've had (somewhat) of a success now.  By uninstalling and reinstalling
 the libunwind-headers, I was able to get gcc47 to properly compile.
 However, now, it seems to have a problem finding a number of symbols from
 the standard library.  For example, it can't find the std::string
 move constructor:


 {{{
 Undefined symbols for architecture x86_64:
   "std::basic_string<char, std::char_traits<char>, std::allocator<char>
 >::basic_string(std::basic_string<char, std::char_traits<char>,
 std::allocator<char> >&&)"
 }}}

 Any ideas if this is occurring for you or how to fix it?
