You have (most of) both. V1 and V2 coexist in the Boost CVS at the moment.

update the boost/mpl directory on the mpl-development branch. From the
boost root:

  cvs update -rmpl-development boost/mpl

To build/run v2 and its tests, in libs/python/test invoke:

  bjam -sTOOLS=msvc test

The source files used in the tests show some examples of how the library
works. Look for the bpl-test rule invocations in libs/python/test/Jamfile,
from which the source file names should be obvious. The docs under
development are in libs/python/doc/v2.

HTH,
