[Boost-users] Boost: unordered library installation problem

I tried building the boost unordered library and i get like this error. exactly how do i build the boost unordered library. 'boost-build C:\cygwin\home\Chun ping Wang\boostBeta\unordered/../boost/tools /build/v2 ;' but we were unable to find "bootstrap.jam" in the specified directory or in BOOST_BUILD_PATH (searching C:\cygwin\home\Chun ping Wang\boostBeta\unorde red/../boost/tools/build/v2).
