As you are on Linux 12.04 as I am your default compiler seems to be gcc 4.6.3.

Try adding this into the compile line when you building your binary file:

 -DBOOST_NO_CXX11_ALLOCATOR

That worked for me on a simple example.  It is buried now down in the thread.

Boost is getting the library version wrong and making some wrong choices.  This fix should get you running.

Best wishes

Are you asking me? If so, how do I check #1 and #2?
