Could you try:

        ./b2 --debug-configuration

This should report where Boost.Build files are found. For me, the output 
is this:

notice: found boost-build.jam at 
C:/Sources/github-boost/boost/boost-build.jam
notice: loading Boost.Build from 
C:/Sources/github-boost/boost/tools/build/src

Where b2 is in C:/Sources/github-boost/boost - so it's loading the
rest of build system from the same place. If it's not the case for
you, see whether you have BOOST_BUILD_PATH environment variable set.
