As far as I know the code is valid C++11 [modulo bugs ;D] Good point
about changing the compiler flag since I am hacking against C++-11
even if inadvertibly being compatible with C++0x.

That's due to the CMakeFile picking up the wrong versions of the
python C lib and possibly boost python picking up the wrong version.
You need python2 versions of these. I just updated the README.md this
afternoon to clarify this. I'm not really sure how to tell CMake to
only use the python 2 versions of these though. I only have python2
installed here [or at least the C lib and boost python for python2]. I
will install the python3 variants of those and try to figure out a way
to differentiate between the two. If that turns out to be a major
hassle I might consider switching the build tool.

Thanks for testing though,

Flo
