C++11 on FreeBSD 10.2

Hi,

I am trying to compile something and I thought I had read that FreeBSD 10 supports C++11 but configure is saying this:

Code: 
checking whether g++ accepts -g... yes
checking whether g++ supports C++11 features by default... no
checking whether g++ supports C++11 features with -std=c++11... no
checking whether g++ supports C++11 features with -std=c++0x... no
configure: No compiler with C++11 support was found
configure: error: Upgrade your compiler. GCC 4.7+ and Clang 3.2+ are known to work.

How can I fix this?
Code: 
FreeBSD clang version 3.4.1
gcc version 4.8.5
 
Whatever you're compiling doesn't care to check if there is actually a g++ command available in the system. You can probably tell it to use clang/clang++/clang-cpp by this invocation:

env CC=clang CXX=clang++ CPP=clang-cpp ./configure

Click to expand...

Now am getting this:
env CC=clang CXX=clang++ CPP=clang-cpp ./configure
checking whether the C++ compiler works... no
configure: error: in `/usr/home/y/znc/znc-git-2016-03-05':
configure: error: C++ compiler cannot create executables
