using nanoseconds with boost:posix_time

I need nanoseconds resolution, and I read in the Documentation: http://www.boost.org/doc/libs/1_53_0/doc/html/date_time/details.html#date_time.buildinfo

that I have to build boost again with BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG defined, but I have no Idea where I should do that, or how the syntax should be. It should be in a jam file I guess. I have boost-build.jam, boostcpp.jam, project-config.jam. But no Idea what I should write in one of those file to make it happen.

According to the documentation you linked (emphasize mine):

To use the alternate resolution (96 bit nanosecond) the variable BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG must be defined in the library users project files (ie Makefile, Jamfile, etc).

That means, it suffices if the aforementioned macro is defined during compilation of your project. You need not rebuild boost itself.
