Storing pairs in a GCC rope with c++11

I'm using a GCC extension rope to store pairs of objects in my program and am running into some C++11 related trouble. The following compiles under C++98

#include <ext/rope>

typedef std::pair<int, int> std_pair;

int main()
{
   __gnu_cxx::rope<std_pair> r; 
}

but not with C++11 under G++ 4.8.2 or 4.8.3.

What happens is that the uninitialised_copy_n algorithm is pulled in from two places, the ext/memory and the C++11 version of the memory header. The gnu_cxx namespace is pulled in by rope and the std namespace is pulled in by pair and there are now two identically defined methods in scope leading to a compile error.

I assume this is a bug in a weird use case for a rarely used library but what would be the correct fix? You can't remove the function from ext/memory to avoid breaking existing code and it now required to be in std. I've worked around it using my own pair class but how should this be fixed properly?
