According to:

http://www.boost.org/more/lib_guide.htm#Guidelines

"The library's primary namespace (in parent ::boost) is given that same 
name, except when there's a component with that name (e.g., boost::tuple), 
in which case the namespace name is pluralized. For example, 
::boost::filesystem."

i.e. bimap should be in namespace boost::bimaps
