Can you try with a new version of g++? When I compile the tests with g++ 4.6, I get the errors that you're seeing. It seems to work with g++ 4.7 through 4.9, though.

I think we just need to change the using declarations to typedefs, since
g++ 4.6 doesn't support those yet. I just a pushed a commit to fix that, so
if you re-pull it should work with g++ 4.6.

Thanks,
Manu

Thanks.
I got it compiled by replacing KType with Typename T::key_type in all places in the files under tests directory
