Build Failure - Build from source

Hi everyone,

I am struggling trying to build mongo from source. I have followed may posts from here and stack overflow but sadly I hit a wall with this.

I appreciate any help I can get.

src/third_party/boost/boost/mpl/aux_/integral_wrapper.hpp:73:31: error: integer value -1 is outside the valid range of values [0, 3] for this enumeration type [-Wenum-constexpr-conversion]
src/third_party/boost/boost/mpl/aux_/static_cast.hpp:24:47: note: expanded from macro 'BOOST_MPL_AUX_STATIC_CAST'
#   define BOOST_MPL_AUX_STATIC_CAST(T, expr) static_cast<T>(expr)
