OK, there's an update in Boost.Trunk to bcp so that it only considers
library source files to be a dependency if a header declares something
that's defined in the source.

As a result using bcp on python.hpp pulls in a lot less.... but:

Serialization still gets pulled in - you may know that you're not using that
particular feature, but as it's #included by the python source you're going
to get it anyway.
MPI still gets pulled in - this is an artifact of some recent changes to
boost.graph (which is used by python) to optionally make use of the parallel
graph lib depending upon some #define. You may know that you're not using
this feature, but you *might* be, so it gets pulled in.

HTH, John.
