[mlpack-git] [mlpack] No C++11 compiler available! (#447)

Hello,

Hopefully this is an easily fixed problem.  I am installing mlpack on my University cluster, and got the following error during the build:

>decato at hpc-login3 in build$ cmake ../
>-- The C compiler identification is GNU 4.4.7
>-- The CXX compiler identification is GNU 4.4.7
>-- Check for working C compiler: /usr/bin/cc
>-- Check for working C compiler: /usr/bin/cc -- works
>-- Detecting C compiler ABI info
>-- Detecting C compiler ABI info - done
>-- Check for working CXX compiler: /usr/bin/c++
>-- Check for working CXX compiler: /usr/bin/c++ -- works
>-- Detecting CXX compiler ABI info
>-- Detecting CXX compiler ABI info - done
>-- Checking for C++11 compiler
>-- Checking for C++11 compiler - unavailable
>CMake Error at CMakeLists.txt:8 (message):
>  No C++11 compiler available!

This doesn't make sense to me, because my default gcc compiler is C++11 ready:

>decato at hpc-login3 in build$ which gcc
>/usr/usc/gnu/gcc/4.8.1/bin/gcc

Any advice on what to check or previous experience is much appreciated, thank you!!
